Y2K-WS6

Intake&Cam advice? 408/FRH 237 TFS heads, etc
OK, I finally pulled the trigger on a set of heads for this car.
The car came with LS3 heads which I didn't want to run. I decided on the Frankenstein Racing 237cc TFS heads. The next thing I need to decide on is the intake as well as the camshaft recommendation... This is purely a drag car, and I want to optimize 1/4 mile ET. I will also be buying a stall matched to this combo as well... PTC, Yank, Circle D, FTI... after I get the intake and camshaft worked out.

Here's the combo:
2000 Formula WS6, 3350 weight without the driver, 8.50 cert cage,
TMS fully forged LQ9/408, diamond flat tops with 3cc valve reliefs, TH400 w/Brake, stall TBD, Fab9 4.11 spool, full tubular K, and tubular all arms front and rear, manual rack, adjustable drag shocks on all 4 corners, 1-7/8" ARH, going to a dual 3" exhaust with X. No wheel tubs.
I want to mill the heads as much as possible to increase the compression as much as possible, as I will be running E85...and want to maximize power. The engine currently is at 11.0:1 with 68cc LS3 heads. I plan on installing the TFS/FRH heads, then measuring PTV, and milling to increase compression to at least 12:1 or higher as PTV allows.

Intake Manifold:
Fast 102 ported with long runners?
Fast 102 ported with med. runners?
Victor Jr. with 4-bbl throttle body (no elbow)? ported?
*I am OK with a small notch on the cowl, as required by the victor jr, but I do not want to eliminate the wipers due to local "street class" rules... (as is required with a larger or taller intake).

Camshaft:
I am leaning toward the LLSR camshaft from Cam motion at this point, The Street King Stroker (single plane or dual plane)... The specs for their single plane version are 246/254, 110LCA, 621/604, and for their non-single plane version are 248/256, 112LCA, 621/604. Actually, these are the specs for their hyd roller cams, and the LLR would be slightly different.

Stall Rec.?

My goal is to run the quickest ET possible with the engine/heads/car combo listed above. I am not planning on any nitrous to start with, but I might add a 100/150 shot down the road if the car isn't fast enough for me.
I really am hoping for low 10's in bad air, and a chance at 9's in great air.

Thanks for any input you can provide!

Someone here did a combo similar and dyno'ed it don't know of any et's. BTR(Brain Tooley) is a good place to start with 1 stop shop and track proven combinations.

For sure the single plane intake with TB
and the LLSR is a great piece for your setup

FAST 102mm with medium length runners, a cooler running intake that won't require chopping of your car, won't require an air pan or 90* elbow and has a wide variety of TB's to use on it. LLSR cam for sure, I'm getting one ground on a 111+4 and it would quiet your sewing machine noise some.

Fast doesn't make mid length runners for cathedral intakes.

I still think the fast is the better option over a victor jr.

I thought he was using an LS3 head, I see he's thinking or using a 237 head.

Yeah he went from stock ls3 heads to FRH TFS 235's. Good move.

Msd intake

I'd lean toward the mast ls3 small bores

MSD Intake, LLSR, and PTC converter.

My $0.02:

Let's start with 246/254-112 hydraulic. To go LLSR you'll be around 252/260-112. However, with LLSR you can go more lift. Likely .675/.650. Another thought on cam specs - if you plan to spray, I'd add about 6 degrees to the exhaust, and since you're taking compression higher, you can open exhaust earlier to blow down. So that's gonna be something close to 252/266-112.

I'd consider a MSD heavily ported intake, Holley 105 to and the intake neck port matched as well.

You'll probably want 7/16 pushrods, so consider opening up the pushrod holes while getting worked over.

Whatever you decide it's sure to be a badass motor.

This is some great information and rec's and I really appreciate all of your ideas and input, gentlemen.

I have spoke with the guys at Cam Motion and FRH and here is where I am headed based on their input.

#1, I am going with the Edelbrock SV intake (with 4-bbl TB) based on what they say will work the best for this setup, if I have to sacrifice the wipers then so be it.
I have a feeling that I will be able to find a way... If not, then the wipers will have to go.

#2, Cam Motion custom LLSR cam:
246/254, 680/663 110LSA 108ICL.
1208 pac @ 1.75" (180/500), morel tie-bars, T&D 1.7's for TFS heads...

Anyone see anything here that looks "way off"??

BTW, thank you guys for not ripping me for not knowing the Fast 102 Cathedral wasn't available with med. length runners. I've been out of the hot-rod game for awhile and just relearning based on today's newer technology and knowledge.

Hoping this setup will produce some good drag strip results!! Time will tell.
"Racing the Drum" is not my priority here, but the best possible ET's with this engine and chassis combo are... as you can see the TH400 and 9" 4.11 aren't ideal for hero chassis dyno numbers!

I will keep you guys posted as things progress.

So you're going with what I suggested in the first place huh. Lmao

After thinking over it a few days and looking today 1st thing came to my mind was carb intake(blk00ss said it also). You have a setup with a Spool diff so it's mainly a Drag set up. Super vic is also a option 2, may lose some TQ if that but has better potential for Future combinations. RPM with Compression = speed. You'll make around what Speed-trigger made depending how in depth you go. 700+ @ the crank or better said around 725 fwhp to 735 no vacuum pump. Your doing Flyin's build with a solid or Speed's with more compression.

Key*

Choosing the correct Stall for the HP,gear, & weight of the car to manufacture a good 60ft is Key.

Let me correct myself. Flyin ran a hyd roller and E85 with a 13 to 1 comp, Speed ran a LLSR cam with compression ratio in the 11ish range. Same hp range , with that said to get the numbers listed you"d need the *compression* around 12 and a half and up. They also used Ls3 style heads you should have a few more Tq"s laying around being that there Cathedrals. But the Hp is in that range. 12.0 and I'll say 715 ish. Sitting here with TxDot. 12hrs @ work, but only work for a hr. ☹️ Lmao

I have the same heads going on my
403. They are bad ***. I went with a ported fast 102 and a cam motion custom spec hyd roller. This is all going on with a f1a this summer. But yours n/a should move good
