4.082 bore x 3.4 stroke = 355.963

356 FTW!

Thanks Dave! The paperwork is down at the shop so I couldn't go find it. That's the problem with a shop where you can't just walk out your back door! Everything you need is there when you're not!

356 is it.

FWIW -- They dyno the motor to 7500 and I know I've never gotten near that. No good reason why it shouldn't be bullet proof.

And we thought he was a just a numb nuts that married up...

I know this probably won't be the popular opinion on this board (given all of the 7,000 rpm engines on jack stands around here :D ), but I'm of the opinion that an engine that makes peak power at a lower RPM is easier to drive on the track than a higher revving engine.

Here's my case... It's easier to get on and off the gas smoothly at say 3000-4000 rpm than at 6500 rpm... This leads to less surprising of the tires and more maintaining of grip easier.

My little truck motor that makes peak power between 2000 and 4000 RPM is a dream to drive, you just have to shift into a higher gear faster. It may get outrun on the straights a bit...but when back in the twistys it makes it all back up again by keeping the rear tires under the car instead of having to pedal it every time out of a corner. Plus (and this is a BIG plus) it's a LOT easier on all of the parts not twisting them so high lap after lap after lap...

Just a thought... Sorry you broke your car Greg, hopefully the carnage is minimal and it'll be back on the track soon.

For road racing I like high revving motors and don't want a torque motor... it's easier to drive at high speeds with a motor that's not trying to break the tires loose on exit. Nothing sounds better than a high revving stroker motor screaming for mercy. Not saying the 355 isn't making torque...

Keeping thinking that because it's true! :thankyou:

Greg, that line running over the header area, that's a return line no, or is it to a fuel gauge isolator?
