question on early style SBC flywheels
 

Im changing my motors from 1989 centre bolt valve cover style smallblocks to early "010" 4 bolt main blocks........engine builder says I'll need matching early style flywheels......can these be bought new??......or do I have to find them used??......how much would they be worth??

Re: question on early style SBC flywheels
 

Those flywheels are available new everywhere, Try Summit, they have them. You also will need to change the balancers and intakes .

Yeah, Summit would be the best bet for those parts. You doin' some trick small blocks?
If you need some MSD stuff I have 2 new.

yeah bought them out of the US last year......had my guy go through them......355s, 010 4 bolt blocks, GM steel cranks, forged 9 to1s, stage 3 iron Bowtie heads,Crane gold valvetrain, 750 double pumpers......dynoed at 360hp/ 405 ft lbs....all done by 4800.......said I didnt think that was very much hp.......he said "these things make tons of torque right off idle, they'll work great in a boat......try them for a year then if you want we can change cams and spin it up to 5500 or 6 and make way over 400hp easy, but I think you'll like them"
