Title: What pistons for 049 bbc heads?
Post by: Ckaz21 on April 06, 2014, 03:18:44 PM

Hey guys I'm trying to figure out what pistons to use in my engine. I want them to be forged cause I'll be spraying it eventually. I have the open chamber 049 heads. Think they are 119-122cc. What pistons will get it around 10:1? Standard stroke/deck.

Thanks

A couple ways to get where you want to be...

Doing it up nice... with a really great bang for the buck forged piston:
If you zero deck the block (which I'd do anyways) and check/cut the heads to 118cc... SRP #212135 for 4.280 bore, #212136 for 4.310 bore.

Minimal amount of work (no zero deck)... with a lowest end forged piston I'd ever use:
TRW# L2349F-(oversize)

Zero decked w/TRW Piston #L2465F-(oversize)


Hope this helps.
