What would you do? Engine question
Just bought a L83 built engine with 882 heads and want to dump the
heads. This motor has stock crank & rods with KB 30 over dome forged pistons. Cam I don't know yet was told it was circle track old school.
Holley 650
With this setup I'm at 10.5 compresson with the 76cc heads. Can't use
the 64cc heads or my compresson is 12.1 Also the engine was built with
only about 11,000 miles and rotating assem. & block are perfect.
so...
Would you use these domes and run 76cc heads or
have the bores redone with new flat tops and 64cc heads?
Street use only, most likely will change the cam and new bearings &
rings. Looking for around 400 hp.
Thanks Chuck

350block 30 over.
Stock crank, stock rods, SpeedPro Flat top pistons 10:1 CR
Sportsman II heads.
RPM Air Gap intake
Holley 750 DP
CompCams 282S cam
300 RWHP and 330RWT can't beat that for an inexpensive 350ci street motor

Lynn, no real budget set.
What I most worried about are the dome tops. Always ran flat tops
and was thinking might go with 195 eliminators. Are they going to clear
without any machine work? I want to run prem gas without any
problems. As you can tell engine specs I'm not good at. Body work
yes
Anyway no real numbers as that is what I'm looking for. Piston numbers
is from KB.
Motorhead I'll keep that in mind
Thanks guys

Learn Something Everyday Myway76 Thanks. Lynn
Depends On Dome Size, Have Had Domed Pistons Flycut To Work With Piston To Valve Clearence. I Built My 388 Using Probe Dished Pistons And Alum 55cc Phase Six Bow Tie Heads 11.1 A Little Odd Combo But A Wild Ride. Good Luck To You Chuck. Lynn
