i have a 331 eagle kit with all forged parts. the pistons are srp flat tops(-5cc). i bought it used got all new bearings to put in it. i have a older set of windsor sr heads(58cc), and i want to use them, but i also want to use my blower(6lb). the comp is 10.47:1 with these heads, and it is supposed to be nuetral balanced with a 28oz damper. the cam i have is a tfs 51402001 114 duration blower cam. does this combo sound good?? i want to make decent power with out breaking anything. i really could use real world advice?????????????

you need larger dish on the pistons 10.5 to 1 is to much for blower application.you'll be running race gas if you try that and don't want to blow something

as far as i know, you cant neutral balance (zero balance) a rotating assm. and then put a 28oz imbalance on it, that would make it shake...
thats a little too high to be safe on 93 octane i think, sure you can do it, its only 6psi (btw you should make enough power to blow the block in half) but you will need a good intercooler or meth injection, meth probally being better in your case and get a very conservative tune.

eagle makes internal balance cranks, if it was internally balanced, you do not use a 28oz flywheel/flexplate or 28oz balancer.

thanks alot. the 331 should much more power than the stock 302(with blower), right?! that way i may not want to run the blower. also why does the rot. ***. have a damper if it's balanced?? it's a romac not sure what type they make. also comp should be good with these heads without blower? last question, the h-beams are marked with dots from 1-8, what the crap does that mean?

yes woody is right, you need neutral balance flywheel/flexplate and neutral balance dampener.

your always going to run a balancer, it will just be a neutral balance, it wont have a counterweight in it, like the external balancers have.

you guys are awesome. i went outside and checked it out it is neutral balance. it should not matter which rod goes where right? they are appearently marked.

if they are marked, it DOES matter where they go..... they are numbered for a reason

woodsy

The ONLY reason I mark any rods on engines I build is because all rod journals vary in size and I tailor bearing clearances to each journal, so if I marked a rod #1, it was because of bearing clearances, other than that it does not matter.
