The 305 shares the same block as the rest of the family of 60 degree V6 engines up to the 478, so that makes it really heavy for it's smaller displacement. If you would like to know more on the development of these engines go to Jolly's 6066 GMCguy website and check out the Sept 1959 issue of Popular Science. They actually tested a 1bbl 305 in a prototype 1959 Suburban, being that it was in a smaller and lighter truck the performance was more V8 like of that era.
Big improvement for sure...and that's with the 4 barrel mounted on a 4 to 2 adapter. It should help even more when I have the intake machined to directly fit the carb. The split exhaust made for a nice improvement as well. I'll check out the sight for that issue! Thanks!
