Re: Ford guys..........E7 heads question
Larry's heads... (I beleive) were untouched as in straight out of a stock car... with 150,000 miles!!! I am sure he will chime in, and clarify this, but "untouched", or fresh, either way, very impressive!!!.

Re: Ford guys..........E7 heads question
Years ago I ran 11.80s with the H.O. combo, but John Presing has been 11.50s at 113 mph using E7 heads. It's hard to compare NHRA and NMRA cars because NHRA cars get slicks and a better drivetrain, but NMRA cars (I believe) can use flat-top pistons and they can run with a much smaller combustion chamber. Either way it's impressive to run 11s with those heads, especially when there are lots of cars with aftermarket aluminum heads that don't run as well.

Re: Ford guys..........E7 heads question
Guys,
Thanks for the input here. I had no intention to compare my thrown together engine, just curious....for fun. specs: 150,000 miles from an 89 GT (sitting under the bench since '99) PB Blaster used as the rings were freed, to turn it over. Took a few days of soaking. E7 heads with plenty of carbon B-303 camshaft (retarded 4 degrees) Crane valve spring kit Cobra 1.7 roller rockers Edelbrock Performer RPM 575 cfm Demon Mac 1 5/8" headers air pan sealed to hood McLeod diaphragm clutch GF 5R Transmission, clutchless 3.19 low gear 4.86 gear in the 9 inch launched @ 6200 shifted @ 6000 crossing at 6200 (tongue hanging out) 3025 pounds 28X10.5 Tires 11.69 and 112 mph. This was a hurry up deal. We thought it would run 12.30 or so. Thanks, Larry Geddes |

Re: Ford guys..........E7 heads question
Larry, have you tried the cam at different centerlines?
4 deg retarded seems alot to me for only running 6200 RPM. Do you use all 5 gears? Is 5th gear 1.1 ?
