Re: Need some input on torque monster 454
I ran a 454HO 425HP/500ftlbs with a M20 and 3.31's. Best run was a 2.0/13.1/107.5, anykind of traction would of gotten a solid 12sec run with room to spare. This was with BFG radial T/A's though. You should do better with the deeper rear gear and deeper 1st gear of the TKO.
If the budget allows, you can get a ZZ502 roller cam for like 160.00 new on a steel core. Its 224/234 .527/.544 110lsa, and the timing set for 40.00 which will allow this cam to be installed in the MKIV blocks, and elimates the need for a cam button. Just need the melonized distrib gear. So for around 230.00, you have a roller cam and timing set that should give you around 25-30 more hp/ftlbs, and eliminate and chances of losing a lobe on that flat tappet. Morel and others now have affordable roller lifters in the 350.00 range. This will be the cheapest HP you will buy, and I see around 450hp, 500ftlbs+.
PS - what OD ratio are you running, the .64 or .82?
*69 CHEVELLE SS EFI 502/T56 Mag/3.90
*11 C6, 6.2, 6spd
*96 Stang LQ9 6.0 turbo - everybody should have one!
