I do not like the loobe seperation on that cam. as for the rocker pedestal option, we leave it open, you need them to run stock rocker armas with our heads, they position the rockers properly. if you were to run aftermarket rockers you would not need them.

thanks,
cary

I'm running 6 more degrees on the exhaust and the car really seems to like it on the motor.

mikeith

what lobe seperation would you prefer....112? or better yet which CAM itself would you prefer w/ the 240cc's to get the best results

good question!

I'm still lost with the rocker pedistal deal I guess what i'm asking is would I need it... would it help me????

GPowrie

Do you plan on running stock rockers? If you do you will need the pedistal option.

BlackSS2001

no I dont plan on it but i'm not sure if I will want the 1.7:1 or the 1.8:1

It said that they came assembled.

Dude call TSP they will max your set-up and get you straight... plus Save you a buck or two good luck.
I think that I remember hearing that one of there guys there is running 475 rwhp with a nitrous tune on the MS4 and PRC stage 2.5 5.3L heads. Then there is TERMINATOR that's pushing 490 rwhp all from TSP

well I can tell you that you will never be able to run those heads on a stock engine with the ms4. You will have major clearance issues.

why such a big runner head?

ETP 215s are designed for 346ci...3.90 bore

Confused, person who thinks bigger is better.

Just hang around here for a while and you'll learn all sorts of things. I know I have.

Phil99vette

Does anyone have any data that supports a small runner makes more power than a big runner? No theories, hard data.

Phil99vette

iTrader: (11)

So if the 240cc head can't fit on a 3.90 bore how do you explain my 346ci 240cc ET head 3400lb car going 10.4 @ 132 in 875' weather?

Phil99vette

iTrader: (11)

The runner size has nothing to do with being used on a 4.0 or a 3.90 bore. My heads were setup with a 240cc runner and 3.90 bore. Jon Kaase did some testing and did not find anything to support smaller runners made more power at any RPM.

You also have a solid roller track application. It does what it is intended to do, go to the track. I'm sure you'd agree that it is not the ultimate mild hydraulic cam set-up. Would I run the 240's on a stock bottom end hydro car? No. It would be 225's for me.

So your saying that the 240 head should out power a 225 or 215 head at any RPM givin the same set-up? I don't agree with that. The smaller head will make more low speed HP/TQ, but the bigger runner head will make more power, just at a higher rpm, at the sacrifice of low speed power.

Your right, I'm not 100% happy with my combo. **** its got less lift than most of the new cams on the market. If I were to do my setup again, I'd use a hydro LSK setup with 240cc heads. Can't remember but I thought brian tooley did some dyno stuff with a larger intake runner with more flow and it picked up pretty good on the dyno.

I'd like to see a 255/263 .663/.663 LSK in there if you don't mind.
