Just drive it!! drivability is all in the tuning.. I daily drive a 370 with a 251/267 cam with a 3200 converter and it is smooth to drive..

And besides that's 495 rwhp so that's about right for a good 408.

So would seeing the motor after 2 years. Ill see if I can get one when I go.

I know for a fact national speed has a reputable tuner and dyno. Ill be going there pretty soon. Thanks for the reassurance though guys. I was a bit worried

Sorry for ANOTHER double post but if I want to turbo it would i have to lower the compression (Granted its high)? Or can I just slap it on and go?

Turbo it and go! My 6L is pretty much all stock short block with 10.25 comp and I run about 15psi through it.

And if you can run E85, you'll be even better off.

620hp is about 495rwhp or so depending on the transmission that foolows. If done right it is ok to be streetable

Have a buddy that runs a 408 TA, he loves it, drives it all over. I bet you have almost no issues with it once you get it in and drive it a bit.

That makes me feel a lot better. I might run it NA for 1 or 2 months before I start hooking up all my tubing I'm used to a cam/exhaust only ls1 with a small turbo. So it drives like stock. I guess I'll get used to the Raw 600 hp then ill want more :/ like always.

I have a 68 camaro with a 640hp na 502. It's fun on the street, but gets old real fast.
