Is this the trade deal you mentioned a while back (engine work for painting your acquaintance's car), or are you getting this engine from a different builder? Just curious... :cool:

does anyone know if the XE268 cam will need a higher stall convertor? I'd like to run the stock one if possible :smash:

Re: Specs on the new engine (Corzvette69)
need to know rear, and driving habits.
a 268xe will work but i don't know if you will be satisfied. Lots depends on how well it is tuned. my xe262 works well, but i am 50 and don't want to squeal the tires(too many cops around here)

Re: Specs on the new engine (Alwyn678)
What happened to the other set of heads you bought. Are you not gonna put a stouter gear under the car??
I'd love to do a more aggressive gear but I do a lot of driving with the car (mostly highway) so i dont really wanna kill myself on fuel

Re: Specs on the new engine (Corzvette69)
i drive mine hard 30-90.
it shifts at 56 into 2nd
90 into 3rd. 3.08 rear.
i roll into the throttle flooring it at 30
a 3.08 is not going to give drag strip launches.
you will need to recalibrate the governor for 6000 shifts to take advantage of the 268xe :cool:

Re: Specs on the new engine (Corzvette69)
The guy i was going to trade with is having second thoughts.. he priced out a 375hp engine and it came out to 1600 dollars. he thought that was a little too high for a paint job so he is un sure.

Deal fell through.. I'm kinda ticked about that too.

Corey, I think you'll be satisfied with the 268 cam. I had it min my 327 before I yanked it out. It had a very noce lope at idle, good torque and midrange, all around great cam. :yesnod:

Re: Specs on the new engine (Corey 68)
The only thing i would change is: Small quench and get into the 10 ish compression . Lopey cams bleed off pressure and you gain back more TQ.
I did a 355 ci motor years ago like yours. They turn a Vette into a real car again. No more sand in the face!
