Horse Crazy: Look out, Ashley Smiley can take any horse and make it perform
MUSTANGS! - speed, performance, and winning are what we demand from them. It's an affliction which a large number of guys seem to get caught up with in their youth and never seem to out grow. No matter how fast we go, no matter how much money we spend, and no matter how much our significant others want to kill us, we're just never satisfied. We just have to go faster and we'll sell our souls to do it. You know how it is when your driving down that certain hi-way with her and Joe Camaro pul...

[04/07/2007] 351 Screamer: Lidio Iacobelli is ready to make headlines again

Author: Dan McClain
Title: MW Founder

Ok, admit it. At one time or another you've sat around dreaming about the ultimate Mustang you'd like to build. Heads, cam, blower, and nitrous included, of course. What seperates Mustang owners; however, is that some make their dream come true. Some owners have connections, some get sponsers, and most just spend lots of money to make it happen. Then once in a while, someone comes along that not only makes their dream happen, but helps to make ours happen as well. Lidio Iacobelli, of Mt. Clemens Michigan, is such a person. He had already owned a Mustang for many years and during the late eighties worked at a Ford Dealership. His dream was not only to build a hot Mustang, but to build a business where he could work with his favorite interest and help others build their dream cars too. So, in 1990, Lidio started his own business part time, Alternative Performance, while still working at the Ford dealership. Through hard work and making lots of noise with his '88 Lx, the business started to flow, and Lidio was able to leave his job to make his business a full time project. The day I arrived at Alternative Performance, I got a chance to see one of the dream machines that Lidio had completed for customer Jeff Richards. A beautiful late model Ford Lightening truck sporting a Kuntz & Company 414 stroker engine. Bolted on top of this 351 stroker was a set of stage I ported Dart Sr. 2.02 / 1.60 heads and a ported GT-40 lower with a Downs box upper. As if this wasn't already enough, this huge motor is being force fed with an S-Trim Vortech supercharger set-up for 9 pounds of boost and fed with 36 lb injectors. This 600 plus horsepower mill should move even this 4500 lb truck into the flat 12's. This engine would certainly be a 9 second motor in most any Mustang.

In the past, you may have seen Lidio Iacobelli's yellow '88 Lx Mustang featured in the hard print magazines. After all, the non-stripped, 3400 Lb car with driver has blistered off 10.60's at 128 Mph through mufflers and Hi-flow cats! However, you may not know about Lidio's other Screamer. His 1979 351 Windsor powered Mustang! This car has put a lot history behind it since Lidio was given the car in 1984, at the age of 17, by his father who purchased it from the original owner. The car was equipped with a V8, TRX package, and for the first several years the car was driven as a daily driver, racking up 70,000 miles. In '87, Lidio swapped out the cam with a performance flat tappet and ported a set of 289 heads for the mill. The car responded by running mid 12's! Unfortunetly, Lidio was in for some disappointment. In 1989, he was in Detroit with the car and went out on French Rd. to street race. He doesn't know exactly what happened for sure, but the ass end of the car came out from under him while racing another vehicle. This caused him to loose control of the car. He ended up smashing into a parked car which took out his rear quarter panel. Luckily no one was injured in this exploit, but as a result the car received it's first new paint job ever. After this, it was time to whip the car back into shape. So in 1988, the car was updated a lot with new gauges, carpet, a dash board, and tinted windows. After this, nothing was done to the car again until 1992 when his Stang received a stock, hydrualic roller 302 short block. A Wolverine camshaft replaced the stock one and the ported 289 heads were kept. To top off the motor, a Victor Junior intake was used and Ford Motorsport 1 5/8" headers channeled out the exhaust. At this point, Lidio was ready to run again and was expecting a nice gain. However, with 4.56 gearing this latest combination still ran mid 12's! Lidio was feeling a little disappointment, yet again, to say the least.

Dissappointed yes, discouraged no! In 1993, Lidio pulled the 302 mill out and in its place went a freshly built 351 Windsor. The crank is a bone stock 351W piece, which has been turned .10 - .10 and is still externally balanced. The short block was squared, decked, and fully balanced with an SFI approved dampener and stock flex plate by the local, Impastato Racing Engines. They cleaned up and beam polished a set of stock 400M rods to connect with the custom forged, Venolia pistons. Finally, a big, solid roller, 274 duration @ .050, .600" plus lift camshaft was installed to make it complete. After which, the top of the motor was treated to a pair of iron TFS heads with 2.05 / 1.62 valves that were fully ported by Ron Sharp's Cylinder Heads, of Mt. Clemens, Michigan, and made to flow a monsterous 320 cfm on the intake and 220 cfm on the exhaust. The chambers on these monsters were also angle milled down to 47cc's to bring the overall compression up to 13.2:1! All this is fed with air and fuel through an analog Holly Pro-jection system connected to a Victory Junior intake with only minor plenum deburring and a little port matching. The Pro-jection unit has been modified by raising the pod .5" and porting the inside of the unit. Lidio believes that this has increased the flow from the rated 900 cfm to 950 cfm which he attributes to the cars excellent throttle response. The ignition is handled by a MSD 6AL box and distributor. All the gasses are sent through a complete 3" exhaust system both on the street and the track. The torque this motor generates is sent through a manual valve body, C-4 tranny that Lidio built himself. The killer power this mill makes isn't the only reason why this Mustang pulls the wheels several feet off the ground though! It's set-up with Eibach drag springs that have airbags, drag shocks, and racing struts. These components, along with some weight reduction makes for excellent weight transfer to firmly plant the cars 10" slicks apon launch. This combination yielded times around the 10.60 mark. This was great until the summer of 1995 when one of the solid lifters broke in the engine and dropped down to break a rod! This caused Lidio to miss every major event with the car that year. Yet again, another dissapointment.

Once again Lidio took the disappointment in stride. He touched up the heads and put the motor back together the same way. He played with the stall and got this beast down to 10.42 at 128 Mph! Soon he will be switching the analog Pro-jection system on the car to the new digital (DI) Pro-jection system. This system should be much more versatile than the tricky to tune, analog system. He feels that this change, along with doing more extensive work on the Victory Junior intake, (that's actually a hundred thousandths off or more from the ports) will enable the car to pick up two more tenths. This year, he seriously plans to make most of the major events with his 351 Screamer, and, once again, make lots of noise. Unless, heaven forbid, he should break something we think he'll succeed! You might keep an eye out for him at one of the big events. In fact, he will be tearing up the track with this car down at the Spring Break Shootout, March 8th - 10th, at Bradenton Florida. Also, even though the pump gas in this motor is mixed with racing fuel because of the compression level, don't think that you won't see it on the streets. This car is driven around Mt. Clemens from time to time, and if you keep a sharp eye out, you just might catch a glimps. Although, it could be a real short one!
