ya, i'd sell the cams. 272's are way too big for your hp goals. Stock heads and cams are good for 600hp easily. I personally would just put new seals in the stock heads and call it a day. I wouldn't replace any parts to save on cash since your power goals are lower.

also, you need arp head studs in there too.

Why do a reflash and deal with a high rpm idle in Cali when BC2's have made identical power into the 700whp range-far beyond what he wants? Not to mention they drive off idle slightly better. Not to mention his mid range with a S/C and low comp pistons will be fawking terrible. Just too much cam for this setup IMO.

Sell them for $$$ OP!

If you want your car to be stealth in california, give me your cams, get a turbo kit and buy another set of oem cats. hollow out one set of cats and cut up your oem intake snorkel to route the charge piping under. Don't forget to paint all piping black/any an fittings/anything shiney.
Turbo kit wise, I'd go greddy personally. Then just get osiris, and make sure your car is nice and quiet. No open wastegates (shouldn't cause any problems until 14psi on greddy kit), and not too flashy on the exhaust tips and you should be ok. Or you could buy aftermarket cats and have them be part of custom downpipes. Also don't drive like a jackass.
aam return line as others suggested is a good idea, and be friendly to your local law enforcement agents; they can be actually quite cool and just as into cars as you or me.
And tbh you don't need aftermarket cams. Stock heads and cams flow plenty, thom made what 700whp on stock cams/heads?

My engine is 175k miles already. Do you think my old cam is still fine?

just have the machine shop check the head and cam journals for clearances. If they are in spec there should be no reason to not run them. Cams don't have a shelf life. you can always buy low mile oem cams from someone for cheap. I have a set with 40k on them sitting in my garage. just sold the oem heads to another member and they didn't want them cams.

If you did use cams (which i wouldn't for that power output) then i would use the mildest cams available. It's just not going to yield you the gains you are looking for with that power for the amount of money the installation will cost.

HP and powerband are 2 different things..

why would he want mild cams on a built that needs to rev out as far as possible?

regardless of HP goals, the supercharger (assuming thats the final choice and also the basis for the BC3) is rpm driven so longer duration cams are a better choice to help the car at the highest rpms that will should be driven at. You wont make a lot of trq down low, so why bother using mild cams that will choke out at max hp?

If he went with a CARB illegal turbonetics turbo kit, then ya, no reason to go with a 272 bc you make peak trq and power way before redline. If he went with a different kit, BC3 would still be valid option.

you're forgetting this is a stock block. He's limited on rpm range and power.

Okay, I've made up my mind. I'm going with Vortech supercharger. Some of you guys mention that my low compression piston is not a good match with the kit. I was able to talk with my builder a little today (He is a RX7 guy) n he told me my piston should be fine. I want to find out what is the maximum PSI I can run on vortech kit? If the boost is low, then will I loose alot of torque? and my real concern is will my 8.5/1 piston produce the power range that I wanted. I can always sell or trade the piston and get a new set, if my current piston is not a good match.

For the cam, I would assume that I might be able to use my current BC3 cam from super charger. But now I want to find out can I use my stock cam, since my builder told me that even though our stock cam can handle 600hp, if I go FI I still need a cam that will open the exhaust valve alittle sooner, so it can breath better. For my power goal, do you guys think is worth putting a new cam if my stock cam are fine?

Also, does anyone know if the Vortech sticker on the blower is gone, but still have the number on it. Can I call Vortech n ask them to send me a crab sticker?

Thank you everyone for your advise.

you can run the low compression pistons, but if you do you'll want smaller pulley, like the 2.87 or smaller to make decent power, ur bc3 cams should be fine with the set up you have if you rev it out you'll make alot of power up top, your low end will suffer though.

no sense building your motor with those 8.5:1 pistons. get the 11:1's now.

Ace, can you link the dynos showing he's going to suffer in the low end? WHat is the the low end? Dyno comparisons from crower dont show any loss of power, and their curves start at 2800 rpms. Who cares about under 2800rpms

oh geez, i thought i was in a different build thread. So many new build threads and "upgrade stock block" threads i was reading on the wrong page. I thought this was the one ppl were trying to get him to use cams on a stock block. my bad

power at 2800 rpm on a 8:5 compared to a 11 at 2800? i dont have a dyno sheet showing the difference but one would assume it would make less

OP, of course your builder would say that, it's the safe bet for tuning, but you won't be optimizing your setup for power...I'm running 9.5 comp on my Vortech and its running fine; you may as well try up for 10's or 11's if you want max power...

And for the blower, if you're using the standard Sc/SCi trim, it's only rated for 54k rpm, which will net you approximately 10~12psi max...in order to get more power without running out of the efficiency of the blower you'll need to either upgrade to an Si or T-trim blower, or the 928 Impeller...

Call Vortech about your sticker...they have halfway decent customer service...
