This combination has worked well in my 302 which freely spun up to 7500 (until block cracked). Driveability was OK, although there was a flat spot down low- maybe camwise, since it's a high-lift high- rev unit.
This combination was NOT run on a dyno, unfortunately.
Hope for input on the matter: putting these carbs on the 347.
Anyone have the jetting for whoever it was who got 595? Hp from his 347 stroker @ 7200 (?) ???? (Now I cannot remember what forum I saw this persons postings....)
Now- I'll go to my workshop in an hour- checking aux. venturi size as a start....
