Yeah it will have a plastic intake. So far I've been leaning towards the small bore ls7 heads 60/40. I'm sure most of you know about Diet Coke's 430ci that ran PRC small bore ls7 heads.. STRONG even before it was at 14.7:1 and super Vic(I think). He ran ran it with a fast 102 and it did great.

Found this guy.. it's a 402 but still ran the type of heads I'm thinking. Small bore LS7 heads and a ported ls7 intake. He was only at 11:1 too, I think I'm going to go with the small bore ls7 heads and let Tooley spec a cam for them. Port matched FAST 102 and I think that setup will reach my goal of 550rwhp.

The cowl does require cutting. I have one of the first LS3 Supervic made and had a super great deal on them, so it beats spending the price for a Fast 102 plastic intake, which was initially my first choice. I don't think I can go wrong with this combo.

LOOK up DIET COKE or John B. 2 jump start a compentent build.
or WKDM may have said it wrong..but take what they have learned and RUN with it all engines R the same ....Just diffferent head designs and bore spacing.
HELL THIs engine comes FACTORY EFI.

550 rwhp is done. Manual trans will make it easy. Get with Mars or Martin with TICK.
The short block - heads - cam
the rest is small potatos.
TRY THIS ON I COPIED JOHN B's BUILD JUST WITH A LQ9 and LS3 HEADS vs LS7
I GOT THE EDELBROCK 4500 1600 CFM T/B I PAID 4 IT IN JUNE.... WAIT TIME IS SOME TIME MID AUGUST... VIC HAS SOME GREAT STUFF BUT THEY SUCK IN GETTING PEOPLE THERE STUFF

I use Chris Franks small bore RHS Pro Elite program on motors like this.
2.155 intake valve with a 270cc port volume.
4.070" bore intake:
.200/163
.300/239
.400/295
.500/341
.600/377
.650/383
.700/392
4.070" bore exhaust no pipe:
.200/117
.300/160
.400/208
.500/229
.600/243
.700/245
Now keep in mind that port VOLUME is LxWxH. Port AREA is HxW.
The Pro Elite RHS LS7 heads have a raised runner for a straighter shot at the intake valve. Air does not like to make turns. Think about trying to take a right hand corner at too high of a rate of speed. You go skidding around the corner and you wreck. Same thing happens in an intake port if the short turn radius is too abrupt and the velocity is too fast. You get turbulence and port stall.
With a raised runner head having a straighter shot at the intake valve, you can utilize more velocity as the air does not have to make such a drastic turn.
Since the port is raised, the port center line becomes longer. Meaning the port is longer. Since volume is based on LxWxH it makes the port look bigger on paper, because it is.
In terms of area though, the port is actually no larger than most 250cc non raised runner cylinder heads.

KCS, are those the RHS small bores you referred to in pms?
And Martin do you mean the RHS small bores have a better advantage over the PRC small bores due to the raised runner? Goals for this are 550rwhp+. Street Racing, weekend car. It wont see a strip ever. Could you possibly pm a price on the Chris Frank RHS small bores? Would like to see what I'd be looking at with that setup.

Got another motor a 440 c.i. that I'm doing the valve train on that will have a set of the 308cc solid roller versions he does as well. Big nitrous motor for Ultra Street.
Haven't used a set of the small bores, but everything we've gotten from him has been exceptional. I would have no problems selling someone a set of the small bores.

I should also say that we had a 416 c.i. 13:1 motor a while back with the PRC 260's, GMPP LS3 single plane, 4150 carb, IIRC it had a 251/263 .624/.624 111lsa cam(before I worked@Tick so can't remember 100%), 2" headers and through a Glide it made 566/456 to the tires.
This car on a .082 jet@3230lbs. on a 275/60 drag radial ran a best of 5.50@130mph.

Thanks Martin for your posts, gives me something to think about before making any final decisions. Its still a little ways off so not in a super big hurry. It seems so far that any route I have listed should make my goal of 550rwhp+. I'm more than likely going with small bore LS7's. Just need to figure out from what vendor..

416
14.5-compression but pumps low due to Denver air(or lack therof)
mild solid roller 650 lift at valve
TEA Tooley prepped 245 Cathedral port heads
Mast intake-1050 holley
Nothing fancy really
last time out in 6100ft of D/A car ran 147mph on motor,so and 1/8 mile times in sig arent exactly accurate/updated
~
Might see 150 this fall if all stars line up lol
Would obviously be well over 150 at sea level nearer 0 d/a or so
