Comp cams 232/236 .595/.598 112lsa XER lobes
Going in a 370 flat top 243'S untouched.
Another question is by running thia cam any ptv issues that stand out if i mill the heads. .010 and by doing so any issues running pump gas? Car is strictly a street/DD. 4.10 M6, LS6 intake

That combo should scoot nicely. There shouldn't be any piston to valve
issues since the 370 will have aftermarket pistons with valve pockets ????
Depending on the efficiency of your exhaust and with a decent tune I would
think it should make 440-450 rwhp.
Also pump gas (93octane) will be fine since compression is in the
11.0 : 1 range.

Flat tops hyperuetic no valve reliefs
just kixking around the idea of milling a lil whole heads are off for thay addes lil bit of compression .its nothing cast in stone just trying to weigh the options.

If you want to do it right, install cam 112+4 LSA, install heads and measure PTV.
Remove and mill according to results found for safe margins and max compression.

Well budget got pissed all over yesterday . So looks like im stick with either 241's or 317's . Which would do better on this motor? Strictly a street motor so keep that in mind . Id like to keep milling to a minimal so i wont restrict myself so much on cams later down the road.
Thanks

317s are terrible for compression. My vote is for the 241s.

Do a LOT of reading, then port your 241's

Thats what i was thi king to that the 241's would do alot better than the 317's. Later thus yr olan on upgrading heads and intake so really not that big of a deal just want something that'll run decent. N im pretty sure she'd be a turd with the 317's on it

mark21742

If you take your time and do some work on the 241's they can work VERY well

Now i just need to come up with a cam that'll work decent with the turd heads thats going on for the time being. Probably end up with an off the shelf cam for rite now.
