I have a 98 Vortec 350 long block 2 bolt mains It only has 9000 miles on it. and a older 350 4 bolt main bare block, I would like to build a TPI 383 with vortec heads I know I'll have to wait for the base.... Or should I just drop the Vortec 350 in and be done with it (after the base comes out) It only has 9000 miles on it. I'm painting my car now so I have some time. Also the 305 only has 50k on it.

Thanks
