Separate names with a comma.
I am surprised your current setup is not on the lean side with a 555 BBC. That is 80 cid more than I had (in 1979) with the same pump, hat, and...
Interesting stats, never thought I would see the day Billet Hemi parts were the same or cheaper than quality BBC stuff. It should not surprise me...
I would say .065-.070 would be safe.
% I have worked for the State of SC for over 35 years; but I am also an artist sometimes on the side. The average art gallery takes about 40% if...
Scottrod, don't beat yourself up too much. My first car was a BB/FC (1977). We purchased a BBC longblock (less blower and injector) from another...
The mags today are hotter than when I raced, so the timing today is a good bit less. But as several have suggested; sounds like you are...
Head studs Long ago I had a Rodeck 481 and a iron BBC spare. We converted the iron block to 1/2 in studs to fit the same heads used on the...
''''''''' old hemi is pretty vague. 392, 426. or?
At Indy 1980 I watched a BBFC owner put Freon(?) or something pressurized in the tank (in the staging lanes in front of everyone). He claimed it...
ratios I think a two disc may be minimal for your app (But I have not raced in along time). At 2200lbs I will guess a 44% 44% (208-144-1.1)...
Faster How much pack clearance do you have in your Crowerglide?
I would get that info from someone that currently uses one or the other as I am sure things RE blower intakes have changed since I last raced...
Blown BBC Catman, what type of blower manifold will you use?
Blown BBC A good cam for that combo going back to the mid 1970s was a Crane R288-4133. I Don't know if that profile still exist today. With a...
Many years ago I used a iron BBC truck block (BB/FC and AA/DA) as a back up to a Rodeck; but with compression closer to what iron468 uses. 1/2...
Sounds like your heads and intake are a good match. In 1980 I ran the almost the same BBC combo you have (-100 cu in) w/ clutch and lenco 3 spd;...
What type of block and intake do you have?
I will guess that bad cylinder is showing most at the shift point. You may notice a bigger drop in tire growth at that point as well.
You may have to make a minor fuel curve adjustment since the 4.30 gear won't load the engine as much.
