"A TR224 on a 346 is (analgous to/the same as) a _______ on a 383"

It seems like a 224/224 cam is pretty universally thought to be 'about average' as a selection on a 346. Decent idle, good powerband, and all that.

Given the extra displacement of a 383, about how many degrees of duration can you add to get a similar performance characteristic as far as idle/powerband, and the like? 228/228? 230/230? 236/236?

I see that most folks run cams in the 230-236 range, But it seems folks that build their motors tend to be relatively more extreme with their cam selection.

This isn't a "what cam should I run in my 383" thread, but just me trying to get a feel for just how much cam the extra displacement can 'eat up'.

Thanks all,

I'd say "230/230"

I have a 232/236 114LSA in mine. It lopes pretty good at 900.

 

I would go with the 232/236, MTI R1. In my 388, you could hardly even tell there was a cam in there.

 

240/240 in a stroker with a decent lobe sep of 114LSA and new lobes

 

Is yours on 112 or 114?


any other contributions? A range of 230 to 244 is pretty large...

What he said! I'm running a 232/232 on a XR lobe and I feel I'm under cammed.

 

mine was on a 112. Ive got a 242/242 595 112 now...still fairly tame, but id say its more like a 230/227 or 229/229 on a 346

 

I have a 236/240 and it is acts somewhat tame. I could go larger but i would get better street manners if it were smaller. Doesn't stall since I got it tuned.
