349 CI on the cheap

Ive actually DONE the 349 / 360 crank stroker build...but it wasnt all plain sailing.

First...I used some forged TRW SP2260 slugs and shaved the crowns down .100th...I ended up with very little P-V clearance.

I have this problem with mine - I can't run a cam over .500 lift.

I used some specially welded 318 heads, but had to take the chambers to 63 cc to avoid RIDICULOUSLY HIGH compression.

So what I have now is:

10.8:1 comp
318 heads (63 cc open chamber)
and can only run a .495 lift cam.


I d really appreciate it if BJR or Moper can help me with the following:

What KB Forged slug can I use witha 360 rod that will keep my comp up around 10:1, but give me the P-V clearance I need to run a .540 lift cam?

Diamonds are NOT on the agenda because of cost.

Hope you can help?
