With thoses piston reliefs I would be tempted to raise it up to 11.5 to 1.

Yeah it let go back in june at midnight madness, **** happens when youre racing. Its all good, its been fun to learn some stuff about these motors on this build and the new combo should work alot better. Plus now with some good rods in it i can put a nice shot of gas on it if i ever get the wild hair to do so.

Just do it. I had been trying to get him to do it since I knew what it was built to handle. Having a built motor is fun. When Futral built the motor in my trans am it was built to handle a 300 shot. Forged LS1 stroked to a 383 with callies rods, diamond pistons, manley crank, and a direct port system from nitrous outlet. It did 452rwhp (on motor) on the stock 241 heads through the yank ss3600. Heads were the next mod before my accident happened so never got to see what it could really do.

Beave

Yeah, thats about where i plan to be on motor. Did you ever run it at that power level? I have a nos kit but im going to wait until i have a better trans before i spray it.

I ran it once. My car was never setup to run 1/4 mile as funny as that sounds with it being a auto with handling suspension but it did a 11.6 on motor and 10's on spray trapping 132mph.

Beave

Cool, yeah it was running 11.9's before as you prob know. Just hoping for solid mid 11's on motor. It will be a fun DD.

Beave

Well its back up and running. I put about 130 miles on it so far. Hoping to get it tuned either this weekend or next week. I will post the numbers up then.

I meant to update this thread sooner. Got the car going and it has about 1500 miles on the new motor now and everything has been going smooth. Here are some updates on the differences.

Old motor- 423whp (dynojet, locked converter)
346ci
unported dart 225 heads
F14HL cam- 230/234 .646 114
Manley flat top pistons 10.5:1
fast 92/92
Best 1/4 mile was 12.02@114- 1.70 60ft

New motor- 405whp (mustang dyno, unlocked converter pulling to 6500 and power still climbing)
347ci
ported dart 225 heads
EPS 230/234 .600 112
JE Flat top pistons 10.8:1
Eagle H beam rods
fast 92/92

Only 1 pass so far in similar DA and conditions as before
11.81@117.98- 1.70 60ft

I did not change converters, still the old vigilante 3200, 3:73 gear etc. Full weight, tools, spare etc not taken out, just as i drive everyday.

I knew the car was faster up top now even only pulling to 6500 like before so i just made one pass as a baseline. Im going to start doing some suspension mods next and take the spare out, tools etc. and see what it does in cooler weather. I have no doubt it has some .60's maybe even .50's on the right day and will prob trap 118-120 in good air maybe higher if i start pulling the motor to 7K. So not bad considering i went down in cam and still picked up some power. The car will stall all motor until tax season then ill probably go ahead and put a 150 shot on it to see how it likes it.
