What kind of cams are you guys running with out flycutting with a 59cc chamber and stock bottom, also what head gaskets are you using? Asking for a friend. Thanks in advance!

 

I'm running a tv2 cam and tfs 215 heads that were milled to 59cc. Using mls .054" gaskets

 

What kind of power are you making?

 

I am using the Tv2 and some ls6 heads with stock mls gaskets.

 

They are milled to 59cc's, and the pistons arent flycut? This is perfect, we were wondering how big of a cam can fit without flycutting on a stock gm mls gasket. He is under the impression he cant run more than a 220/224 .550" lift cam, while I am trying to tell him can run a bigger cam, I'm just not sure how big.

 

With TFS heads you will be able to run a bigger cam without flycutting because the valve angle is different on the TFS heads (I think 15 degrees, but for the life of me cant remember!)
Also black01_WS6 what are your PTV clearances like? Have they been measured? What size valves are you running in the LS6 heads as that will dictate alot with the PTV clearance as well.

 

Really the only way to tell safely is to measure the PTV clearance. Honestly I havent but I know Im getting close with my 5.3's. There are alot of factors that you have to look into and really no motor is going to be exactly the same as the other. The bigger duration you go the more of a chance you take.
A 224ish cam is safe, but I personally just for piece of mind wouldn't go much bigger than a 228/230 with around 600 lift.

 

I'm running a 230/234 .612/.598 112 on 59cc heads while using a stock head gasket.

 

224/224 .581/.581 @ 112 with my Patriot Stage II heads (59cc) and .40 gaskets...

making 458/410 to the ground...

 

I have the partior peformance stage 2.5's my PTV clearances were close but I had a little room for a larger cam, but not much larger. I think I have a pretty good setup that the parts work together not just thrown together.

I think a G5X1 would be perfect with sopme 59cc heads.

I think for a street car, a small cc head and a mild cam works better than the huge donkey dick cam only cars out there. It all comes down to power under the curve on the street.

 

tv2 with 59 cc patriots and stock mls. also have morel lifters

The TFS heads are 13.5' which is why you can run a bigger can. I'm hoping to get my car back from the shop tomorrow. Everything is still being installed. I'll post back when I get the car back.

 

thats pretty much of the setup i was going to go with just milled to 60 cc to safe. i have ported 5.3 heads now but was looking for a little more power. def. let us know how you like it

 

stock bottom end here...

mods in sig pic...

 

228 228 .576/.576 here with no issues

 

Are these the older PP heads with the welded chambers? I am running the same cam on a 111+2 that will cost me a little PTV but was advised more than once to run a .054 MLS gasket and not mill to stay safe

BTW, wicked cam huh

 

A good deal of opinions in this thread lol.

 

To be completely honest with you, I'm not sure if they are milled or welded. I got in touch with one of the guys from speed inc and he hooked me up with these heads and a 224 cam at that time. This cam is on 112 +4 using stock head gaskets. I personally never checked PTV on it, my shop checked everything and said that it would work fine....so I believed them. I'm also running mine on a ls1 intake () so I don't get to enjoy the upper rpm range like I should get to. The ls1 intake killed me on the dyno! What kind of numbers did you get? Do you have your dyno sheet? What's your setup like?


This cam is sweet!! It's amazing, and pulls forever! I still enjoy driving this car everyday! If I cared about gas mileage I'd get a Prius or something.

 

my heads are the old welded up style 59cc heads. 035 6.0L truck casting heads...

i havent had a single issue with them to date and they have been on my car for 2 years and roughly 12,000 miles...

 

I would not run a 230 cam on 59cc standard casting.
Not enough PTV. and not a TV2 112 (at least not safely). Clearing piston (not hitting) and safe PTVC are 2 different things.
