![]() I went 7.601@92.2 last night, had to launch very low RPM to hook, crappy track. That converts to a 11.86@116. Got some more work to do but I think if I could have launched at 6000 like normal the 60ft's could have come down and times would have been better

![]() You leave at 6000!!! must be a manual cause that would be one converter to stall 6000! And no wonder you blew the tires off why so high? And tell me your rearend/driveshaft/axles/mounts/etc isnt stock! lol

![]() Why not so high? I usually bogg down under 6k, the ET streets really grab for me. No, nothing in the rear is stock, only the T-5 is completely stock. I'm looking at getting my axle tubes welded next. I've launched at 6k many times and left hard and straight.

![]() Never been on a dyno, but the 331's like to rev, ask Jeff! lol he knows about high revving, anyway, I decided to shift there because I can feel the torque die off there, it pulls hard up top till then.

![]() Lots of guys launch at high revs like that. USMC is not out of the ordinary there.

All motors are different. You can build a motor to make power to 4,000 rpms or 15,000 rpms, you just need the right machining and parts.

![]() Negative, I do not have the money to throw away a motor. I invested in everything forged and top of the line internals so that my little stock block 331 will last as long as I can get it to. Besides what is the fun of racing if your not using the powerband? Want us to shift at 3000 to save the rods? I wouldn't need slicks anymore either, or axles for that matter, matter of fact, I could put everything back to stock and have my engine last foever! WOOHOO!

![]() I shift my 302 at 6k, though I dont launch real high. (normally around 2-2500 when im street racing) I really didnt invest like those other guys to make sure my motor stays together that high, Im just to dumb to care. Plus if it does blow up, its a good excuse to build another motor!!! Though I am too poor to go through that again for awhile...
