whats up guys well its time for me to now disassemble my HCC set-up to go with a cam more suited for turbo use as the cam i was running will be to large for the TT kit i am putting together the specs on the current cam were 242/248 with lift around .580 on a 113lsa i am retaining my stock bottom end this cam worked well but continued making power past were i wanted to rev my stock shortblock (6800-7k) in turn i didnt want to spin a bearing.

so i wanted a cam that will give me a little more midrange power and doenst take as long to make power in the upper rpm range, i was looking for something that will get me going a little earlier and top out around 6000k or a lil more, but not start making power from 6k upwards you know.

a heard alot about exhaust overlap and that i dont want to much of that and to keep the LSA's around 113-115 and that it doesnt need much duration to work with TURBO. this is what i know but what i dont know is where to even start. who makes cams which i could look at, does anyone have any suggestions for me.


BTW: i am running heads with a port job similar to a stage 2 LE's with stock valves and 918's beehives.

also i wanted to know what would be the best head gasket to use to drop my compression from 10:8-11:0 to lets say about a 10:0 if possible right now the bottom end is a stock lt1 bottom with the heads milled 20 thousandths i am currently running the mr.gasket .26 crush gaskets but someone told me there were some .41 crush thickness gaskets that i can use to bring my compression ratio down, but exactly how much will it bring it down?

any guiding light here will be helpful guys BOOST gurus please chime in.

 

^ not a guru, but I'm trying.. What engine?

The following is an LSx based engine.
I asked a vendor a similar question and they advised me that the 225/225 .581 .581 113 was a great cam that actually outperformed the split duration cams. W/ great drivability also..

If you want a broader power band, you could do the 114LSA. .581" at the cam would be .929" lift at the valve. The 918's are rated to .600 right?

As far as head gaskets.. I think the Cometic is a nice piece. I've seen them used in HUGE cam applications. But running 11:1 compression, I'd have to say a metal gasket. The Cometic one I used on my friend's build was a flexible type. Not metal. -Not sure if they're just one kind.

I think someone on LS1tech figured that the .040 Cometic gasket would bring the compression to about 10.5:1... NOT SURE, tho!

 

well i am working with the LT based engnes ....
