Nah I'm thinking more like a 1.125 or so piston

 

Don't know were ya gonna put it in a 8.2 deck height unless ya go with a sub 3" stroke. Wind it up baby- to about 20,000RPM's.
Or is this a new definition of "Pop Ups"

 

I think that will be my new goal, a 4.185 bore X 2.75 stroke 302, with SB2.2 heads. Run it to 10,000 RPM and spray all the way!

Now I just need to run out and rob a bank.....

 

When ya find that bank get some for me too.

 

3.5 stroke, 4.185 bore, 5.4" rod, 1.125" CH = 8.275 deck

Now put SB2 or 15° heads on it and it's a neat little motor.

With Dart making billet blocks now for LS1's it would be easier to do that on that platform.
