Hi guys I am looking for a replacement cam for my 350 chevy small block. My specs
350 sbc 9:5to1 CR
Dart Iron Eagle Ported 200cc heads milled to 69cc combustion chambers
block was decked 10cc
Quick Fuel 650 DP Q series carburetor
Edelbrock rpm performer air gap intake
Hei with 50,000 volt coil all timing in by 3000rpm
Forged flattop pistons.
I currently have a comb cam big mutha thumpr roller cam and it may sound good but it does not perform like comp says it does and it has over 34 degrees of overlap at 50 duration wich is too much for me engine.
The bmt cam is 243/257 @ 50 with 537/517 lift I believe. I don't take this thing to the track just a weekend type deal. I wanted to use a comp cam 288xr 236/[email protected]
50 with 520/540 lift but I don't like there cams being made of austempered iron. So I looked at isky's website and i found a relly nice cam that is almost like the comp cam but theres is billet steel and they state they can be used with stock type iron distributor gears wich I got.
It specs at 234/246 @ 50 with 530/550 lift. It has a 110 lsa with Intake open 7,Exhaust open 47, Intake closed 53, Exhaust closed 13, that is timing at 50 duration.I feel with only 20 degrees of overlap on the Isky cam will still give me a decent choppy idel with not being too much. I checked summit racing and there website does not have hardly any isky cams and jegs does not either. How long does it take to get a cam if ordered from Iksy themselves? I have never got one of theres before.
Will this cam give me at least 10 inces of vaccume at idle by chance? I only have 6 with the big thumper cam and for performance wise it sucks. It makes decent power but not what comp cam states it does and it sures the hell is not streetable like they claim it is. I want the cam to match good with what I got but have a nice choppy idle as well but not too much overlap. My oldest crane roller cam 234/242 @ 50 539/558 had only 14 degrees of overlap and was on 112 lsa and it was close but not quite what I wanted for the sound but it performed way better then the comp cam.
Thanks guys for your opinion.
