Is that real bad and what is causing it
Couple of problems here maybe you can explain; you say .775 lift "hydraulic roller flat tappet cam", Which is it, roller or flat tappet? Then you call out .550/.550 lift. It would help if you told us with your build if you told us what cam manufacturer, seems a cam with 244 dur and .775 lift is an odd grind. With your experience building performance engines over the years, you should be able to provide more accurate information on your current build.

Also, it wouldn't be a huge expense changing out pistons. The cam, if it's a true roller, a little pricey, but a deal breaker.

Got it, flat tappet or roller?

On the nitrous issue, it makes a ton of power but can be brutal on parts, and not as fun as full time boost on tap, if you go nitrous, use it with caution. Problem is E85 isn't available everywhere, although cheaper than gas, it takes a lot more of it to get to the high power levels, similar to alcohol.

Flat tappet. I was going through some paper work and trying to find more specs but i have so damn much. How ever i did figure out after looking through some invoices at part numbers and such, Being that i have 0.240 thousand dome forged 38 cc pistons, and 118 cc semi open combustion chamber heads, i am actually closer to 10.8-1 compression ratio. I really want to make this blower work! But nitrous would probably be easier.

look on the summit websit my heads are the edebrock 60555 part number. The cam part # is cca-k11-213-3
Look on the summit racing site and you can see the exact parts. It is a slightly different cam than i thought, but easy to mix everything up when i am building so much crap. lol.

heads look good,like support over 600 hp N.A.
The cam ,if changed to a roller would likely add a fair amount of power,same with a Victor intake.
The personality of the engine would be different,moving the power band up in the range

Thanks Vinnie, What do you think would make a better more radical cam? something by voodoo, or Thumpr cams . Any thoughts on a certain one. And as i mentioned earlier i do have that Offenhouser intake little taller and single plane, for higher rpm's. Any ideas?

sell the offy and peformer and get a vic
a cam like this solid roller

120173-12 NA 273 279 241 247 .646 .646 112 108 .022 .022 1,2,5
2800-6900 Fair idle, Street/Strip, strong mid range torque. 10.0:1 CR, 2800+ stall.
about the same advertised duration at 050,but nothing like your cam at all.Your cam probably starts to roll over at 5200.this Cam would pull another 1200 rpm and it would already be making more power than what you have when your cam is finished.

If you decide you really need to have a boosted engine:
Maybe use two baby GT45 turbos and make 900 hp with 12 pounds boost

That Cam actually looks and sounds pretty nice for this application. So you think go with the solid huh? Hmm,, They are better performing but a little more maint. Victor JR on the intake. K i'll look into them too and see what my options are on them. Thanks Vinnie.

ok taking all into consideration from all advice. Going much larger with cam, and sollid cam and lifters, what is your thought in me using a tunnel rum, duel quad, for this upgrade? is it a wise decision, or should i keep it single carb? if i don't use the blower then i will want to maximise my potential as much as possible. Advice? I do fancy the duel quad look as well.i want to increase my mid and top end torque as much as possible, and should i use 500 cfm's if going duel, or 600's? and will this create a dead spot in instant acceleration, i also want to avoid that? Thank you all so much

That cam I mentioned is still quite small,,,
If you go dual quads,I think 2X750 as a minimum.
we have a few guys here that use street tunnel rams,they will jump in fast. I used 2X750 on a street 350.
sounds like you are making a big change in tune as apposed to a moderate upgrade

Yes definately a big change in tune and a big upgrade. i fugure if i am going to change i am going to make it a good one and be happy with it, so i don't have to keep dumping $$$$$$ in it every week because it's not at my level of expectation. I want it to launch hard out of the hole and still set you in the seat at 70 mph. with no hesitation or complications. so i think i will try the duel tunnel with duel 750's. what would you recommend for model on the carbs and intake? edelbrock, holly, ?? and what cam enters your mind for radical acceleration and full performance. I have a brand new 2,400 hughes stall for my th400 already.

I also have abrand new b&m th350 built to the hilt i could throw in it that would give me a little more snap. But don't think it would hold up very long against the big blocks abusive attitude, lol
