Hey Ryan, thank you getting back to me about my previous question about your big block build! I have pretty much wrapped up my build as far as I can get before I have to leave for deployment, but have a few more questions that was hopping you could answer or give me some insight and your opinion on.
My combo is very similar to yours
454 bored.030, decked.010
Same SRP pistons 26cc dome
781 heads with large 2.25 int /1.9 exh valves
Lunati voodoo hydraulic flat tappet cam
Edelbrock victor jr single plane intake
- did you ever calculate your compression ratio? I got the same pistons but used 781 cast iron heads. My block was decked.010 and heads.005 so was curious what my C/R would be? I m guessing around 10.5-1
- leads to my next question is did you ever check piston to valve clearance? I ve heard of guys running even bigger 32cc done pistons without problems so figured the 26cc will have even more clearance and be no problem, but figured I d ask cause better to be safe then sorry haha.
- and lastly my big dilemma is I want to run fuel injection. I bought the heads and intake (Edelbrock victor jr single plane) as a combo deal so figured I d use the intake. But it s the large dominator bolt pattern and the only Holley fuel injection kit I ve found that fits dominator is the 4500 series that supports 800-1500hp and is 1440cfm. Do you think it s going to be way to much for my combo and might be better off just getting an adapter plate and running the standard Holley sniper 4150 series that s good up to 650hp?
If so I know them adapter plate are around 2 thick and do you think I would then run into any hood clearance issues? I dk have a fiberglass 4 cowl on my 1971 Chevelle so have some extra room.
I know it s a lot but honestly don t really know a lot of gear heads yet here at where I m stationed now so any info or advice is greatly appreciated! Thank you and hope to hear from you.
