Well mine is not what I call high comp as its 10.6 comp. I run a 440/493 combo that's a .030 over 440 with the 4.15 crank. I run on 92 pump since we have it in my area but it should run fine on 91 or less even as it has no detonation at all with 36 total timing. Here is the basics:


440 block with 4.15 crank

440Source stroker kit with D-dish pistons for 10.6 comp and .046 quench

The basic Indy EZ heads with some work from Dwayne Porter

Dwayne Porter solid flat tappet cam that's 264 & 270 @ .050 and .585 & .592 lift with a 110 LSA on a 106 ICL

Indy dual plane intake and 850 Holley DP

Mallory dist with MP orange ECU and 36 total timing

TTI 2" headers and the full 3" exh out the rear of the car with Ultra-Flow mufflers

Hughes roller tip rockers and Manton pushrods

Its in my 63 Sport Fury running a 727 with a 9.5 Dynamic converter and 4.30 gears using 30 x 9 Hoosier tires. I race my car just as I drive it on the street which is through the full exh on 92 pump. I don't change anything at the track as I built mine to race and drive without making any changes and I usually drive it to the track. Actually its never had race gas in it and I have never uncapped it. So far its run 10.70's . Ron
