346 chamber heads(3.9 bore) on a 402 stroker(4.0)bore??'s
Hey guys, I've been doing quite a bit of reseaching lately on a good larger ci package for my 02' ZO6. I'm currently running ETP 215 heads at 59cc on my 346 with Cometic .040 gaskets and a G5X3/114 cam.
My questions are:
How would these heads work in conjunction with a 402?
Should I consider having the bore opened up, or is it not to big of a deal?
How will the smaller 215 runner negate performance and will I see numbers similiar to others with 402 setups?
I'm planning on running this combo with a ported Fast90, and a G5X4 cam.
I have given some thought to the L92/L76 combo, but would like to try and sell my 3k+ worth of parts so my wife doesn't kill me for purchasing parts that I don't need....
TIA,
Alan

My advice... if you're going to a 402, sell your ETP's and get some L92's sell your fast intake aswell. Get the L92 heads, and the L76 cam, put the money you got from selling your heads, intake, cam into your shortblock. and have 500+rwhp
