Default 396 ls engine?

is it possible? I have a friend who wants to make an ss clone out of his 69 camaro, but he wanted to update it with some goodies. His plan was originally a large cube sbc or mid sized bb, but my swap got him thinking about an ls motor. so we got to thinking and thought it would be cool to make a 396ss camaro with an ls motor, but I don't know if you could do it. isn't a stock bore 6.0 stroked a 402? any thoughts?

Greg

As close as you're going to get is a stroke of 4.125" with a bore of 3.905". I found an Eagle LS crankshaft with a 4.125" stroke, then you'd need a 4.8, 5.3, or 5.7L block to bore to 3.905". That ends up being 395 cubic inches.

I don't know the numbers(bore x stroke) but, Mecham Performance offers a 396 package

I was just using that to show that a 396 LS could be built. I think it's overpriced also, considering an LS7 in the crate is only 14 grand. Have your friend build a 427 LS motor, and make a Yenko clone

IIRC the late 60's 396 was actually a 402, but advertised as a 396 because GM had a factory passenger car 400" size limit on their engines until 1970. Then there was dealers with special packages like Yenko who dropped in 427's in Novas, Camaro's, and whatnot. Vettes could have 400+ inch engines because they weren't "passenger cars". Could be wrong, read it in an old muscle car book a long time ago.

this was my other plan, I remember reading this too, but just thought it would be too. the 427 would probably be out since were just going to be working from a 6.0 block and heads.

thanks guys.
