I asked a well known Ls1tech member for a can spec that would it my build. And the answer he responder with confused me alot.

I told him I'm building a Lsx, ls3 heads, VICTOR JR, TH350,3.42 gears and would like to avoid flycutting/notching pistons.

He responded : the only issue with single plane intakes and ls3 heads is ptv clearance. There is no room for the camshaft to scavenge the intake opening and exhaust closing events to properly scavenge the intake runner and produce torque on par with that of a long runner intake manifold.

????what????

There are big people running Victor jrs that haven't flycut their pistons and are running decently. Then i asked if switching to a dual plane instead of the single (since I haven't purchased the upper half of the motor yet). But since its taking him about 3days in between to answer I thought I'd ask the broad majority.
When I sent the same specs to TSP they speced me a 235/239 can and said ptv clearance would be fine. . @
I'm just confuser now.

If your not drag racing your vehicle all the time a dual plane is the way to go. The single only shines over the dual after 6500+ rpm. If I did mine again I get a set of good proted cathedrals a dual plane and enjoy the low end grunt. Mine doesn't open up untill 5500. It pulls hard down low too but I'd gain with a different setup

What is the 1st sentence your saying? Dual plane for the track or for the street?

I'm setting mine up to b a MONSTER

How much converter do you have? TSP knows what they are talking about. They have tested to see what cams will clear.

Common sense tells me the "bit" is supposed to be "not". B is beside N on the keyboard, and I is beside O as well. Just like the "can" spec in your first sentence the N is beside the M on the keyboard.

I agree, dual plane for the street, single for the strip

Not to pick on anybody but that is just silly talk. Pick the intake to match the rest of the set up. There are lots of good reasons to run a single plane on a street motor.

I knew you would say that, lol It doesn't make sense to me to run a single plane on a 6500 rpm motor, the dual plane will make more all the way to that rpm usually. A true street car will benefit more from a dual plane imo. But opinions are like ********, so pick what you think will suit your needs

Oversimplification. Displacement, stall converter, gear, weight, intended use, camshaft all play a part. A generalization like that just might get somebody the wrong intake.

I understand that, and totally agree, but I still say a true street car will benefit from a dual plane. To me a street car guy doesn't worry about all that stuff. Maybe I should call it a cruiser instead of a street car, sorry for the derail, Ill shut up now

I don't have a converter yet until I figure out my cam.
With that 234/239 can they recommended about 3600 stall

speedtigger

I think you might want a 4000 or more with that cam. You could certainly run it with a 3600, but it would probably be a little lazy down low. What is the Lobe Seperation Angle and Intake Centerline for that cam?

savage9scorpio

Don't have an intake centerline but 235/239 .639/.623 available in 112 Lea or wider. The techee specd me to go 112. The only thing about this can I didn't really like was there aren't to many ppl with drive experiences. I don't want to get it and it has terrible driveability everywhere under 3,000 rpm. . But its the only one I've been specs so far
AND THATS WITH THE SINGLE PLANE AND A STATED NO PTV CLEARANCE ISSUES.

If you care about drivability and want to stay with the 3600 converter, you should get a cam like 3 pedals used to run. He had a 227/235 LSL custom Comp Cam. I think he ran 10s on that cam in his 67 Camaro. Martin at Tick sells a cam just like that and lots of guys have had great dealings with him.

I think this is it:

I wish I could find who you speak of just to ask if he had to do any notching of the pistons to use this cam. .

dogsballs

lol, driveability issues under 3000 rpm with those cams, yep they are big suckers for 4000+ convertors. imho will be ok around town with tight convertor, but will want to rev. with the square port heads you don't really need to a lot of cam to make them go. i've found compression and good fuel make a bigger difference. heck i ran a stock Ls2 cam on a 6.0 with ls3 heads (just milled 100thou) and ran e85 and punched 400rwhp.

i'd be looking at 210's or even 220 cams, with a 30thou off the heads, still will have plenty of ptv.

Who exactly am I looking 4?
Martin@tick is the person I mentioned that confused me about the ptv and single plane. Is it him? He must b a busy Guy cuz he takes days to respond.

I'm 22 so I may b a little impatient, so ill try to chillax .. but who to pm?
