I'll be putting together a stroker short block next spring to replace my tired stock bottom end. I'm going to be on a budget though, so rather than stepping up to an AFR LT4 head or similar I'm going to have to stick with my Lloyd-ported 2.00/1.60 heads. Peak flow is 276/192 @ .600 lift.

Just wanting a cam recommendation from the experts. I like a healthy lope but am not one to tolerate big driveability problems. This is a problem when trying to make big power with limited head flow.

How much can would I need to put 425 to the wheels? The car is an M6 and runs all the bolt ons, long tubes, 58mm Tb, 1.6 comp pro mags, etc.

Would a 236/244 pull off what I'm asking and how tame would it be in a 383 vs. what I'm driving now (224/230 in stock bottom end with same heads). The upside is the car is NOT a daily driver anymore.

 

Not to be too obvious, but what did Lloyd suggest?

 

I didn't think to ask him.....the heads have been on the car for 2 years as-is, which was well before he started offering all his packages. Not that he wouldn't give me a suggestion...

 

I would go with more compression the next time around. Maybe 12:1 and cam it to run on pump gas. Big cams and low compression don't run too well, just ask me.

I can tell you this: the bigger you go, the more low speed drivability you lose all other things being equal. The cam I have now could really use a 4.10 gear and a 4500 stall. It doesn't get 'on the cam' until around 4000, then it starts pulling good. Tuning is also more involved. I just got another cam from BRE so hopefully it will work better this time, but I need to spend some quality time tuning the thing at the track, dyno, and street also.

It's not easy to slap a bunch of well-known, high-dollar parts together and go fast. At least not for my average butt. Some of us have to work on the total combo to get it right along with some tuning.

Play with engine analyzer and see what you come up with. I've spent countless hours on it.

 

I've done a little work with EA on it. Seems like I have to make massive jumps in duration to make more peak power vs stock displacement. The extra cubes do bump up area under the curve a lot, though, which is nice

I hope Savannah is working out for you dude.

 

I did an 847 off what lloyed susgested and preety much what you have listed and did 417 with an auto. I know everyone wont make that but with a M6 it shouldnt be any problem
