I was thinkin about using the same heads I did on the other engine's,15* heads then use a sheetmetal intake.

But right now I'm resreaching this out.
Does he not have a power goal? Mostly street, track, ? 1/4 mile or road course?

What works for nitrous and superchargers is not especially friendly with turbo combinations. Ring location, pin height, stroke and rod length. Turbos are "closed loop" power adders that are abit more sensitive to intake and exhaust design, head flow/efficiency vs cubic inches etc.

I prefer a single plane intake vs the sheetmetal deal. We've seen better air distribution using a common plenum/elbow setup. See pic


Depending on how the design ends up, the cam can be very mild to moderate as compared to a blower/nitrous cam. Once you get a better idea of what he wants....feel free to post up some ideas and we'll be glad to help.

He want's the same power level has the 648 thats in it(1000hp),which honestly is overkill,it's around town,cruise night queen,trailered everywhere else.honestly the only time it's been run hard is the couple times I have driven it,he's one of the just because it looks cool kinda guys.

With what I have gathered here and some other site's I think 70mm would fit just fine,and if I get the go ahead,I'll throw some combo's together and see what you guys think.

Well I thought for sure a turbo would be like a nitrous set-up and love air flow.I wouldn't have guess'd a single plane style intake,would work best,I'm sure it's subject to application too.

they definitely benefit from good heads, but the intake is not as critical as a nitrous setup as the air going through the intake is under pressure, not drawn through like a n/a or nitrous setup.

it sounds like you need to sell him on a particular idea and stick to it.. and weather the displaement is 496 or 509 really wont matter, the 496 might be a little more street friendly and will rev slightly less agressively.. and thus be a little less hazardous to drive but thats only marginally.. i think you need to move on to asking hom decitions he can actually make.. does he want the intake polished or satin... and so on... and tell him that you will make the engine fit his needs and ask him to tell you what they are...

i think ka67_72 did a set of equal length BBC turbo headers in stainless.. send him a PM and see if he cant whip you up a set.. looked awesome, the primaries were alittle to large diameter if you asked me.. but it sure looked bling!

Well that's my plan I tried to sell him on a sbc deal,but he thinks since the car has a bbc it will be easier,but he doesn't understand the whole engine compartment will have to redone,I've been playing with a combo to sell him,I just don't have all the details worked out yet.

well, what if you had a lunchbreak meeting where you with some visual aids.. mockups of turbos, aluminum flex-heater hose, pictures and carefull explaining made him understand that a big block would empose some bad-compromise inducing space constraints.. you might even use a tape measure to get the point through... and sell hom on what ever you think is the right package... i mean you are the pro..

but a twin turbo big block.. it sure sounds cool when you say it out loud

Well kinda the way it went when I tried to explain everything,I'm just going to build the motor.He's talking to acouple guys on the actual turbo set up.the crap we go through for friends is unbelievable sometimes.
