Hi everyone.
I am from Hemet, CA and happened upon this site while doing research on big block chevy's.
I am a hobbyist and have had my 67 chevelle since 87. I learned all that I know from the old guy down the street. He was a chevy guy and taught me how to pull out engines and I have been hooked ever since. I love working on my chevy and doing all that I can do on it to the limit of my know-how and knowledge. My first car was a mustang 2 with a 4 banger and then I exchanged it for a rallye sport mustang 2 with the 302 in it. I sold it and bought a vega and put the small block 400 in it. I never got it running because I saw the chevelle and bought it for $700. I put the 400 in the chevelle and have had it in there until now. I am older now and know what I want out of it. A BIG BLOCK. I bought a 96 suburban with a good running 454 and sold my small block. I plan on making it simple as possible. I snatched all the top end off to just the short block to run a carbureted setup.
This is where I need some help. This car is for the street with occasional bracket race use. I want it driveable with vacuum for the brakes. I just want a mild cam and heads and just want to be sure that the components I choose can just bolt on with no major problems like punching a hole in my pistons. I have limited knowledge about machine work, clearances, etc. I have absolutely no knowledge of big blocks. These are the components I chose so far:
Brodix Race Rite heads summit part no. BRO-2061000 - 119cc Chamber, 270cc Intake Runner
Camshaft summit part no. NAL-12366543 - Duration at 0.50 Lift 224/ 234, .527/.544 in. Lift
Edelbrock Perform RPM air gap intake summit part no. EDL-7561
The chevelle has a turbo 400 with gearvendors OD and 3.73:1 gear.
Questions:
1. Can I just bolt these heads on with this cam and not worry about the piston to valve clearance? Stock pistons are flat with valve reliefs.
2. I noticed that the pushrods are different lengths. Is this common to all big blocks or just to these vortec heads?
3. Will the aftermarket heads use the same mounting bolts as the vortec heads?
4. Should I try for more compression with 110cc chamber heads?
