1971 chevelle ss 402?...

[TURBOSCHILZ]

Also I need to know about cylinder head parts as well... What were the stock length of the pushrods, did it have long slot rocker arms, 1.7, guideplates, etc.?... And what engines from what years would be interchangable for parts if I were to purchase used?...

Don't have numbers for the pulley's, search ebay for some and they may list the numbers. Any long water pump, 396, 402 or 454 pulley's from that era should work. For 7 blade fan, 772, check Ebay and craigslist. The 772 was used for a number of years. I have one with dates of 73, most people are looking for correct dates for 69 and 70 so I got mine cheap. The rockers are 1.7 with guide plates. Most parts from a early 454 or 396 from the 60's are the same. Push rod length? Check Summit for stock replacement push rods, the specs will show the lengths. Chevy built millions of 396's and 454's and most parts are interchangeable. There are a lot of minor differences over the years so would need to know what parts in particular.

I moved distributor, valve covers, fan and fan clutch, alt, power steering pump, headers, engine mounts and probably more from a 71 402 to a new GM Performance 454 crate engine a couple of years ago. Finding parts that will work should not be a problem.
