Please define untouched

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.

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: what gear were you running and what RPM did you go thrugh the traps at? I have been struggling to get mine to work right all year, and wandering what gear to use witht he new setup

Re: Ford guys..........E7 heads question
 

NMRA F/S guys run a 58cc head, but none the less, the things they do with a stock combo, as awesome

Re: Ford guys..........E7 heads question
 

Freddie,

4.86 gear

6200 rpm in the lights

Re: Ford guys..........E7 heads question
 

Larry: thanks... are you still running the Kuntz motor? Car looked great in Chicago.

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 ?
