The 403 in my openion is a very good engine it has a widowed main web and simeased cylinders but its a good engine if u put some pre 73 chevy 350 heads on it it gives it about 9.5-1 instead of 8.0-1 stock or sumthign like that but check out www.442.com then click olds FAQ and go to 403 and read that its some good info'
