ive spoken to both companies over the phone c.o.m.e say thier manifolds sit lower then harrop (i would only care if i cannot fit the harrop an carby under my standard HDT reverse scoop) my engine is in the build shop at the moment, mild 355 in VH sl/e over a $1000 for the harrop an $800 c.o.m.e anybody thats been here before, please share your thoughts Burgz

Torque Power? What kinda power you looking to make? If it's mild, use a TP High Rise Dual Plane... Found to be nearly as good as the Single plane, just better down low and not as much revs.

i havent considered the torque power yet kane. im hoping for 400 at the fly. my sle's fairly lightweight running a built trimatic an vl-t borgy instead of a heavy t400 an 9inch so im hoping for a good little revvy engine without busting my budget

i have a mate running a come racing manifold on his 355. very responsive and well made, this engine made 482hp @ fly. torque power is another option definetly.

the c.o.m.e option is the 1 im going for :-) priced the same as the torque power. bloody harrop... unless a mint example pops up second hand there just too pricey for me

I wouldn't with your fairly sedate setup....

do you think a good dual plane is the way to go?

I think the hi rise dual plane is, you've got the torque of a 355 with a mid sized cam, you're not looking to rev the ass out of it

What is the height difference between the come and the harrop? I believe the harrop and torque power are both around the same height, ie wont fit under bonnet and won't fit under vk scoop either. 400 at the fly is nothing extreme so might get away with not using a hi-rise. I'm currently using the torque power hi-rise and making about 520HP.

Use a high rise dual plane.. should fit under.

I'm at the same crossroad. Just sold my Harrop Single plane due to the 180mm deck to carb base height. I got it under the HDT scoop with a inch spacer but had to choke it with a 3inch air cleaner and a bit of bashing of the lid at the front for street duties. If I changed the fuel line, I could have taken out the spacer and spent nearly $300 on a K&N X-Stream 9x 2 3/4in air filter assembly it would fit easily under the scoop. The Earls fuel line was fouling on the runners due to being fairly low. You would want to stick to a 9inch filter as it isnt so much the overall height that is the issue, it is the height of the front of the filter vs the rake of the bonnet. So, the wider the filter, the bigger the battle to keep it covered. My combo was in a VB with a non genuine/ exact replica HDT scoop, so a VH is the same, as the carb to bonnet clearance was the same in my VH. I havent rung COME yet to get the manifold height, but there is a VK in issue 187 of SC (TUFGM.8 on the cover) that has the COME single plane, a Barry Grant carb and what looks to be a 14x4in K&N filter assembly under the bonnet, so am happy to go that way.

Read this PLEASE! http://www.torque-power.com.au/ms_hi-rise_dualplane.htm Quote: WANTS AND NEEDS Craig says people commonly ring asking for a single-plane manifold. He asks what they’re building and the answer is often a 355ci stroker with something like a Crane 286 and pocket ported heads. They may have a 3800rpm or 3500rpm converter or perhaps even a 2500rpm unit. He explains that they don’t need the single-plane high-rise, the high-rise dual-plane would better suit their needs. At the top end both manifolds will be within about 10hp of each other but the dual plane will make perhaps 30-40 ft/lbs more torque. The good thing about the extra torque is that it helps the converter work better. This means that instead of running a 4200rpm or 4500rpm converter with a single-plane high-rise, a 3500rpm unit might remain a workable proposition. And keep in mind that the less a converter slips, the cooler your transmission fluid remains. Previously, a person with a 355ci stroker would have had to go to a high-rise dual-plane if a 240deg @ 0.050in camshaft was used. Nothing else would allow the cam to make the power it was capable of. However, as we’ve pointed out, the single-plane is actually a bit too big for the combination and would have reduced airspeeds too much for optimum results. This new manifold addresses that issue and fills the gap in the range of products available for the early motor. In our opinion, it’s definitely worth a look. Craig is eager to point out that development of a product like this is a collaborative effort and wouldn’t have been possible without the efforts and assistance of all the companies mentioned. The results of this united effort are available for $830 in either single or dual-plane form.

That would be best for his, I run a large solid cam and pull every part of the 7500rpm limit. Best to get cam specs put up VH747, as said, the dual plane meets most applications and has proven results. It isnt all about rwhp figures and time slips if it is a streeter. With a decent setup and a dual plane, you could be pulling out of a corner with more power/torque at lower revs, and it could be a more responsive car with a more enjoyable powerband Some original photos have not been recovered yet.

^ cheers. im going back to engine shop end of the week so im going to have a word with them about manifold choice..
