Another Ford in GT/AA
 

#1 qualifier, #1515 GT/AA Jeff Lawrence, Qougue NY, '88 Mustang 9.153 off a 10.40 index -1.247 under. This Ford must be a pretty stout piece! Anyone know what engine combination he is using? Thanks in advance, Don Jackson

351 cleveland. Jeff has ran this combo for years, he used to run a 85 mustang, but I guess he updated it or bought another car. Very Very Fast Car

Re: Another Ford in GT/AA
 

Jeff has been running his ride in GT/AA for years, it is definently a nice piece. He recently updated the body 88 Saleen spec's this year. Anyways, please guys don't get Jeff any horsepower, we rarely have anything to brag about in the Ford camp let alone a Cleveland no less.

Great Job Jeff, keep representing the lone loss Cleveland Combo!

What year and horse power rating is the Cleveland?? Thanks in advance. Don Jackson

Re: Another Ford in GT/AA
 

The Boss 351 (rated at 330 hp was never built in production as a Automatic same with Boss 302 4 speeds only and the 351's were NEVER Built with a Holley 780 this carb deal ia a paper combo again, in production they had a Autolite 4300 D Ford's answer to the Rochester Qjet).

Re: Another Ford in GT/AA
 

Those Clevelands are killer engines. The head flow and the small cubic inches makes it a super combo. We watch our Ford buddy win every night against the SBC's at Indy 5/8 Oval for years. Jr Blair. Steve Blair his son drives now. He used to match race a 427 SOHC 57 T-Bird against Bob Glidden in the old days. They win in the Truck Series the last few years.

Re: Another Ford in GT/AA
 

jeff's 351 is not a 330hp it is a low comp/hp combo that came with a auto

Re: Another Ford in GT/AA
 

I wouldn't call 285 factory hp and 324 NHRA horsepower a low rating. The engine Jeff is running is an Closed Chamber combo that came in 71 Torino GT's, Mach 1's, Mustangs, Torino Cobra's etc...... compression ratio is 10.7 for the 285/324 versus 11.0 for the 330/330hp Boss.

Re: Another Ford in GT/AA
 

The Holley and alum hi-rise intake came to be because it is what came OEM on the rear engined Italian car Ford used to import and sell called a "PANTERA" which were 351 Cleveland powered. It was deemed legal sometime around 1974 when I was working tech with NHRA. NO I didnt have anything to do with it although I did inform Tex Miller of the allowable change back then when he was still running the Torino.

Re: Another Ford in GT/AA
 

For a cylinder head that has the volume of a Cleveland, with a large valve size, and 11.0 to one compression, 324HP makes it a pretty favorable combo. I dont know many heads that will flow what a Cleveland head will. They are about the best out there.

Re: Another Ford in GT/AA
 

I wish I had a set of those good CC Cleveland heads and intake for my old ride.

Re: Another Ford in GT/AA
 

Actually the Cleveland heads are not that big, a lot of cc but they are only 2.80 Inches of cross sectional are at the short turn.

Re: Another Ford in GT/AA
 

2.8??? That is good for about 470 inches to 6500 RPM with zero limitations on HP. Gesso Pete, we are more like 2.2 with a 14 degree valve angle and a hundred more cubic inches to do the same thing. Want to know the equation for CSA required to prevent limiting HP?

CSA required* = bore * bore * stroke * RPM/0.00353*(614fps)

*minimum cross sectional area throughout the length of the intake port. For those too lazy to do the math, there are calculators where you can just plug in the numbers required. (If you want to calculate fps numbers that is fine, just remember that it is required that you double measured fps to obtain actual.)
