: 454 external balancer recommendation
I'm building a Early 70's truck 454 for a street/strip car. What balancer do you all run or recommend? Externaly balanced. w/ a M21 4 speed. Here's my combo and thanks for the help.
2 bolt main 60 over 454 (468)
Stock cast crankshaft
Stock rods w/ ARP bolts
Probe forged pistons w/ press fit pins (10:1 comp. w/118cc head)
Stock (like new) flywheel off of a 1988 mercrusier 454 (boat motor)
The rest of the motor will consist of The summit/dart iron rectangle port heads or maybe the new patriot aluminum heads. With a mild solid roller cam. 6500 rpm max. Roller rockers, Performer rpm air gap intake with 850 carb.
Dave Hopkins Dec 3rd, 07, 2:01 PM WHats wrong with stock damper? Is that flywheel externally balanced? Question on your combo, have you thought this out? Rectangular port heats and air gap manifold, 850 carb sounds like a 7,000 RPM combo, cast crank, stock rods and mild cam sound like a 5,500 RPM combo. I would take one route or the other;
1: forged crank 7/16 or better rods, rectangular port, air gap, 850CFM, 7,500 RPM combo, or
2: crank, rods that you have, oval port heads, 750 CFM, performer manifold
My own piece is coming together, .070 bore, KB pistons, 9.6 to 1 CR, Edlebrook heads, performer manifold, 750 carb, Crane Hydralic roller cam, everything programed around a 5,500 peak power

wtf???????????
Which balancer for a external balanced 454? < thats the question. Thanks for the other replies. and yes I'm going with a scatter shield. Didn't really think it was a smart idea to use a 30 year old balancer.
