Hey guys, I knew this was the place to come when I thought of these couple of issues. First, I'm putting in a block from a 1970 chevy c10. This means that it's a two piece rear main with a driver's side dip stick. The oil pan that came with it won't clear the k member and my current 305 has a one piece rear main with the dip stick on the passenger side. Basically I'm looking for maybe an older pan that clears the k member or a good aftermarket one.

Next, I'm building a 355 with 2.02 heads and a comp cams 12-242-2 camshaft. Should I go with a higher cfm carb or will a reworked quadrajet work?

Any info is helpful, thanks guys!

 

Just get an 82-92 F-body pan for a 2 pc RMS block. They were factory from 82-86. Otherwise you can get an aftermarket one anywhere.


What are "2.02" heads? You mean heads that have 2.02 intake valves put on them? You can do that to any old awful crap cylinder head and it wont make it any less awful or crappy - what are the casting numbers on the heads? Most heads that are just called "202"s dont make for stout engines, though. It's usually a way for machinists, mechanics, or just sleazy bro's to sell you worthless junk heads for big prices just because they put 2.02 inch intake valves in them. It's a lucrative, effective method for making money, even if a bit dishonest.

The xe268 is an excellent cam for a stout 355. I'd seriously encourage you to go to a roller setup, but if you insist on flat tappet the xe series is a good modern grind. Just make sure you take all the precautions and run break in oil (or zinc additive - like Comp's Break In lube) during break in and afterwards and break it in properly.

'82-'85. '86 was the first year for 1-piece rear main seal.

You will also need a 2-piece RMS flexplate/flywheel. If you're keeping the TH700, then a flexplate for an '83-'85 f-body V8 will do the job.

Headers solves the dipstick interference with the exhaust manifold problem.

A q-jet can handle that engine with no problem.

 

Well first off, I would have just swapped oil pans to the 2 piece rear main for a camaro but the dip stick is still on the wrong side of the block. The heads are from a '72 corvette they have 64cc combustion chambers and the 2.02 intake valves and 1.6" exhaust valves. I will have full roller rockers on them. I have the flexplate for a two piece rear main and was mated to a 700r4 previously. I just get the feeling that a qjet will maybe hold it back from it's potential? Maybe it's just me.

 

If it was me looking at roller rockers vs a roller cam,knowing the price of the rockers would have me well on the way to a roller cam,I would suggest the best purchase would be the roller cam.Just like what was posted before this.The cam profiles on a roller cam is a true benefit aside from all the other things.
You said it was 64cc heads.Venture a guess at the C/R??.I would guess it would be in the neighborhood of 10.0.That should dictate which cam.

You either have 72cc 993 heads (junk) or 75cc 487X heads. Seems the 487X heads are okayish heads, just large combustion chambers. You may want to go smaller on the cam unless you can get the compression ratio up to the mid 9s.

 

At 750 - 850 CFM I don't think so.
Plenty of BBC performing nicely with Q-Jet

Do the calc and see how much CFM your engine can actually move even if it was a full race engine

The heads will give up power wise before the carb does. If you're doing a street car yes you will probably give a few hp up compared to a holley but the mpg will likely be a lot better too as will general drivability.

 

The oil pan from any '70-'79 Camaro 350 should fit perfectly. Both your block, and your third-gen.
