Thread: Head gear for old 327

Tweet

Hey guys just chasing some info if I could, I have a 327 in a 78 camaro, runs good and has large chamber heads fitted to it, the engine is a pre 68 because it has the old style bolt on oil filter, which ive changes to the spin on style, the heads are large chamber 76cc as well. Ive just aquired a set of heads and camshaft out of a smashed 350 engine, it had done 12000 mile when the flywheel let go and destroyed the gearbox and back of the engine. Now the heads are steel pro toplines 64cc chamber units 200cc runners with big valves, they also come with yella terra roller rockers and the camshaft is a comp cam 212-12-2 which has a duration of 280/280 and a lift of .480 and .480. now for any gurus out there can you see any problems I may encounter fitting this stuff to my current engine. Doing the work is not a problem Ive done it before as Im an aircraft mechanic and have all my tools, the problem is all the above info goes way way over my head and I need advice, anything will do,
Thanks in advance
Steve

Steve, those parts will fit fine, however, be sure to check the rocker arms in regards to ratio. Stock is 1.5. The rockers should be stamped with the size. Anything over that and you should check piston to valve clearance and your pushrod clearance. With the higher compression ratio, you might have to burn better gas and adjust your timing to suite.

Thanks for that mate, Im not to fussed if it ends up destroying my bottom end,good excuse to go out and get a new short block and strok it to a 383. I was just a bit concerned with swap overs like the cam out of a 350 would be the same fit as a cam out of a 327, I understand the performance is different but the actual fit. theres just so many combos out there it doesnt hurt to ask to start with, a mate had his 327 done and had 350 pistons fitted by mistake, when he tried to start the engine he had about 75 psi of pressure in the chambers and couldnt start her. The rockers are a brand name yella terra which is an australian brand and they have the number 5 stamped on them so Im assuming there a 1.5, because of the price of fuel Ive had this girl running on lpg for the last 10yrs now, IVe been told compression is good for lpg and ideas
Thanks steve
