I figured as much, but the TBI intakes are aluminum, and a dime a dozen. At one time they made a spacer so you could modify a standard small block intake to work with the newer cylinder heads.

New motor. After unloading it the other night.
(Thats a gsxr600 powered banshee in the background.
Heads off. Reason why is i noticed a rocker that was VERY loose. Not even close to 0 lash
New dual plane manifold for the swirl port heads
New toy

I got pipe..... though, whats the difference?
Kaiser85

Pipe is ID. Tube is OD.
Example. 1-1/2" sch40 pipe is really 1.9" OD
Ahh well that makes sense. The pipe i bought is 3/4", with a 1" od. (Thereabouts)
Yep. Pipe is designed to flow fluids/gas so size is determined for flow rates etc.
Tube is more structural based. Sorry I work for a plumber lol

sorry if i missed it but what are the specs on the engine? .030 over 350?
Kaiser85

Yes. Its a .030 over 350. I think that puts it at 355. Im currently in the market for a cam/lifter package. Itll be for swirl port heads (weak version of vortecs 87-95). What cam did you use? Specs? (Yours is a 400ci?)

I like the specs on this one so far. Thoughts anyone? Its mating with a dual plane air gap intake (180°), and factory swirl port (aka center bolt) heads.
I think its an 8.5 cr motor

or

still not in stone yet though, shopping around.

Yeah youve got a 406, so its kinda an apples to oranges comparo. If it were me, id go with the second one, as it seems more of a lower end cam. But its not me. Lol.
Mine is a driver, so i want SOMETHING, but obviousy nothing too radical. 1000-5000 rpm would be ideal.
For some reason, .430 lift, 210 duration seems to make sense for my motor.

Also, the jegs site states lift with 1.5 rockers, whereas the summit lisys the EXACT same cam lift with stock rocker arms??????
Seems to imply the stock rocker arms are 1.5:1 ratio arms???

Geez. Learn somethig new every day.
If it has swirl port heads on it, it is probably a roller block, not?

depending on if you are replacing them or not they sell 1.52 or 1.6 rockers (or higher) that you can use to get more out of your cam.

Martin, no, it is not a roller block. Its actually out of a 70 z28 camaro. At least, thats where my reasearch led me.
Wage, do you know the formula to find lift with 1.6 rockers when advertised lift is for 1.5 ....?
