5.3 Build....
5.3 Build.... Im planning on building a 5.3 LM7 for my dads 80 Camaro. So far what i have is a stock bottom end 5.3. My plan is to mill a set of 317 heads I have .030". Install a 2002-2004 LS6 cam and LS6 intake to the top end while leaving the bottom end basically stock (will be installing new bearings and re ringing the pistons though) What do you guys think of the combo and what would you do different? Im hoping to make 350ish HP with it.
317=71cc chamber
243/799=65cc chamber

ur scr will be under 10:1 even with milled 317s
what yr is ur 5.3?
the dish piston 5.3 are around 9.4:1scr with stock 706 62cc chamber heads.
so u will drop the scr even more even with milled 317s if ur 5.3 is dish piston motor

Verdad Gallardo my 5.3 is a 2004. CR is 9.5:1 with the stock heads (61cc chambers) im thinking i should be around 9.2:1 now with the larger chambers. Its cool though cause i want to run 87 octane pump gas in this thing. I think i should hit the 350-380hp number still though
stock manifolds,intake and exhaust, ls6 cam with tune. so i think u should have no prob. hitting ur goal. u may have to use ls2 head gaskets though. or may get away with h.o. 5.3/5.7
I plan on using the ls6 cam, intake, obviously the 317s, long tube headers, with a 4l60e
ls2 gasket 4.045 bore .051 compressed. lq4 gaskets is same bore but .058 compressed
the 317 heads came on 4.00 bore engines and came with larger bore gaskets obviously. compare the chambers and u will see the difference.
may need 4.0+ bore gaskets with 317 heads and 3.78 5.3 bore.
the 241 came on 3.9 bore, so thats y used 5.3/5.7 h.o. gaskets.
