I am running a 350 with what I was told was 360hp? No Dyno so I do not know? I have a Richmond 4 speed with 3.08 gears. I run a 66 Chevelle everything stock as far as the chasis and all go. If I were to get it to hook up what should I expect for ETs ? My elevation is about 1000ft. I am guessing mid 14s? Does that seem right?

High 14's to mid 15's depending on traction. It probably wouldn't take much to get mid 14's. The 3.08 gears will make it hard to launch without spinning.

Where in Oregon are you?

This is a bit of a shot in the dark, but it sounds like 14s are there. Does the Richmod 4spd have a very low first gear? That might make up a little for your tall rear gears.

Do you have slicks? If not, I'd say the best you're going to be able to wring out of it is something in the low 14s.

Just a guess.

Hi TH, I looked at your pictures and was surprised to see a two door sedan. This is a very rare car indeed. I guess i'm a bit off the original subject so here goes as to the guess about this gentlemans Chevelle. Back when these were new i ran several in my '66 Olds 442. Most were no problem at all. With the high gearing its probably going to be on the slow side. My guess is 15.5 - 15.8 depending on how sound the engine is at about 95 MPH. I also had a '68 Chevelle 350 H.P., SS 396 with an automatic and the standard 3.31 gear and no posi-trac that ran a best of 14.4 @ 99 MPH. the Olds pulled better on top end though as the Chevelle went dead at 115 MPH.
