59cc head guys......
Trending Topics
You guys that think that just because a cam clears that it is safe to run it need to take a basic engine building course or something.
A 228 cam will clear 59cc heads but will probably be kinda close on stock pistons.
I was running a 232/236 .585 cam (pretty much a TQv2 I believe) on some 57ish cc heads with pistons with -2cc of relief. I actually measured my clearances and I was pretty much right at your safe clearances(.080 Intake/.100 Exhaust). If I had stock pistons there probably would have been some contact.
My point is you shouldnt ask on the internet if it will fit, you need to take the measurements on your particular setup and if its too close you need to decide if you want to run it like that or you would rather change your setup slightly to give you an accepatable clearance.

i remember talking with you quite a bit about the 231/237 cam. the guy i sold it to is now trying to sell it over on Ls1.com, since he sold his TA...
It will clear ok, I just recommend you measure your clearance when you do the install for piece of mind. Its not hard to do.
that is exactly what i got except ported advanced induction heads, so looks like its gonna be the 228/228 588"/558 on a 112 for me

Also guys check your DCR. If you have to high a DCR, you are going to run into detonnation issues.
Or you'll be forced to run lower timing to compensate and therefore negating any benefit of adding coompression.
Choose your parts carefully based on the fuel you'll run as well.
