My number 2 son has a 1970 GSX STAGE 1. Yeah i tried to teach him better, but you know kids. Anyway after addressing the inherent oiling problems and adding an intake carb combo it is a road ripper. Runs 12.80--12.90 not to shabby for 4050 pounds. Almost as quick as my 324---but old age and treachery wins out. What the hell was FLINT thinking with the front rope deal? We found a seal that fits .....#470543 FEDERAL MONGREL or #450446 NATIONAL. Reworking a set of 430 heads now to help pile on more torque----BUICKS can be fun as you well know.
we'll be back in my buddies 70 gs 455 soon, he just picked up a new block and gonna throw it together. were going to use his old heads that are race ported from some guy in georgia and add a few things more. hoping for 11's but I just wanna see it on the sreet again.
SORRY----NO GUITAR could not carry a tune in a two bushel basket. Seal is rubber\steel and is driven in from back to front. Coat with aviation cement and pound away. Thanks for the tips.
