I need some info. I have a 396 block. I bought a set of std 402 pistons and rods from another hamber. I have a366 steel crankshaft and a set of small chamber 396 heads. If i bore the block will these parts work together? Also i have a CRANE cam it is stamped with blaZer 292-2H anyone know the spec,s on this cam? Is it a solid or hyd cam? Would it work in this engine with a edelbrock low profile 2 four intake with carter AFB,s? OldWolf
Might work, you'd want to get it balanced though. 366 pistons are really heavy. Cam might work, but I would not put a used cam in...
It should a 402 is just a .030 over 396 from the factory. I believe stroke is the same on 366 396 402 and 427. mat
402 is a .030 over 396. IIRC the crank is the same from the 366-396-427. I'd go with a new cam and lifters, just to be safe. Heads should be good. watch the compression ratio with todays gas. Depending on the year of the block you might need the groove in the rear journl of the cam. 65-66 used it for oil to the lifters. It was changes to an in ternal p***age in 67. Good luck on the build. jerry
The cam has never been used i bought it at a estate auction along with a lot of other car parts. It was in a cardboard tube but no spec sheet. OldWolf
Be sure to have the block bored to the pistons. 402 pistons are a couple of .001's off one way or the other (don't remember which) from .030 overstock 396 pistons. Larry T
366 and 427 TRUCK blocks are .400 taller in the deck height....they have 4 ring pistons ,use a taller distributor,and wider intake manifold....If ya ever see a hogblock intake with 2 therostats thats what it is.Otherwise the 366,396,402,427 all have the same 3.76 stroke...454 4 inch stroke...never been into one of them 502s so cant help ya there
Thanks for the info. I went out and looked at the engine and got some numbers. The heads as3993820 and on the block above the oil filter it is cast HI Perf and below that P*** K21 . At the back it is cast3969854 Any info wil be appreciated.I have built many small blocks.However my experience with big blocks is limited. I just want to be sure that this hodge podge of componets will work ? OldWolf
Any 366's I've built are total orphans. The crank seems the same as a 396 until you try putting a bellhousing and flywheel on it. The flywheel is too far back, away from the engine. Nothing but truck stuff works. Starter, flywheel, everything is different from any other BBC I've seen.
That's interesting...I have several 427T steel cranks, which are functionally identical to the regular 427 p***enger cranks, except of a different alloy. Didn't know the 366 cranks were odd. Even regular 427 p***enger cranks are different than the 396/402 cranks....one of the 427 counterweights is thicker, to address the heavier 427 pistons. They can be easily balanced to work in a 396/402, though.
From my 1980 Crane book: Blazer 292-2H specs: 292/304 218/230@.050" 114* lobe separation .510" .527" lift Very good camshaft, even by todays standards. Matt
I had this cam in my 402 back in the day. The motor was a bit tired but still ran 12`s in my beat up Chevelle. It was a good running engine, easy to tune and with open headers it sounded good. Idle was smooth, did not have the over cammed, badly carbureted smelly exhaust, lumpy idle characteristic of an engine with miss-matched parts. IMHO perfect for a stock 325 - 350 HP 396-402. I had a 780 Holley and a Torker intake. It took it out of a 70 1/2 RS Camaro. I bought the car for the engine. My 427 build was taking a bit longer than I estimated and I wanted to race. Yes, the Camaro had the split bumper. In retrospect, a numbers matching car that I should have restored instead of parting out and s****ping. Such is life. The Chevelle cost me $75, the Camaro $500 I think.
I know it's an old post, but if you used the 402 pistons in the truck block, wouldn't you need longer rods as well?, or do the truck block pistons have offset pin location?
