11.92 e.t. is darn good for a 400 hp 327 in a full interior chevelle

Guess you answered your own question then! JUST USE AN E.T. CALCULATOR!

It certainly is. Motortec magazine had a nice article on a 400 hp G/S Nova that ran 11.1 @ 118.

Unless your chevelle is drastically lightened, there's no way it runs 114mph in the 1/4 mile with only 400hp. Maybe 400 hp at the rear wheels!

Brian, thats what I was thinking.
onovakind, was that 400 rear wheel hp?

Jason, I'm not an electronics fan when it comes to figuring that out. If ti took into consideration the tranny gear ratios, converter and rear gear,height of tire, etc., I would have more faith in them.
Thanks
