    Oh, 8.5:1 compression.

    No issues. Idles fine, runs fine, frightens small children and makes alleged better cars cry on the street.
    Did you omit one important aspect of this engine? Mums the word...

    The TP dual plane hi-rise will fit under the bonnet of a VH with a drop base. The low-rise might be more suited though.

    That's what I was thinking, surely it has some form of boost.

    Yeh, 8.5 to 1 comp seems very asthmatic

    Yes, it is a boost motor.

    There is currently no forced induction on this engine.

    It is far from asthmatic.

    The point is that a well set up car and good attention to tuning can make a lousy engine look good and if I didn't tell people it had 8.5:1, no one would know the difference sitting in the car.

    It runs as well as any dual plane would despite everything being "wrong" for a single plane.

    Nope, I just buy stuff because I thought it might go up in price, which it did... I've had Harrops, hywinders, and vic jrs, super vics for everything else... I dont buy dual planes, unless I had a truck that needed to tow or carry loads etc...

    People want some low down TQ, when in reality an engine with a single plane on street tyres will break traction too easily already.. I want the power up past the lower end 4000+

    I figured for $500 Iím having one of these single planes and Iíll use it on my next 355 build. Once I get all my bits sorted Iíll start the build process this winter.

    This whole a dual plane is only good for low down torque and a single plane is only good for high rpm hp is a myth. Thereís plenty of single plane engines making good low down torque as well as dual plane engines making good higher rpm hp.

    Iím certainly no expert but thereís a lot more to intake design than single/dual plane. Thereís runner size/shape/volume, plenum size/shape/volume, port entry angles to name a few. Iíd argue that some of this stuff is more important than wether the intake is single or dual plane.

    Well price and under bonnet fitment is a concern a lot of the time... But a single does have an advantage with line of sight and entry angles a lot of the time, a dual does a 180 turn... People can and will purchase whatever manifold they deem fit at the end of the day...

    Cheers guys for all the advice, my main concern is keeping everything under the bonnet that is why I am considering the TP low rise dual plane, I also have a 3000 stall converter so i'm not sure if that will make any difference to my choice in manifold???

    Use a low rise single plane.

    Iíve got a TP Dual Plane High Rise on a 355 with VN heads (small roller cam) and with a small drop base air cleaner it fits no drama in a VK.

    If you google some manifold heights there is a list on the net I found (I should have saved a copy) that compares the Harrops (single & dual) , the single plane COME, the Edelbrock Air Gap & Single plane and the Torque Power Dual and single planes.

    I noticed you said Cam is 230 - 250 @ .050 duration. There is a big difference between the two. If you have a 230 @.050 you will get away with the 3000 stall in a 355 if you have at least mid 3ís in the ass end.

    A 250 @ .050 Cam will want a lot lot more than a 3000 stall to make it go... and it will also want a single plane intake.

    Yep... some need to be burnt, to learn.
