SLO247 1,713 Posted January 19, 2015 A few years back I bought a 350 holley and it came with a manifold to suit. Its a Torco or Torqo brand manifold. Looks like a copy of the redline 2 barrel, its for an alloy head. Anyone know about these? Googling turned up very little aside from they make or made speed parts in the US. I was planning to use it with the holley, extractors, 2.25" pipes and thermos (to hopefully free up a few more HP) on my XD 250. Share this post Link to post Share on other sites
gerg 10,871 Posted January 19, 2015 If it's anything like a Redline, it will probably starve 1 & 6 above 4 grand. Still, better than a stocker. Post some pics, that may help. Share this post Link to post Share on other sites

Clevo120Y 815 Posted January 20, 2015 I personally wouldn't use that manifold, the transition to the runners are too square and would flow quite poorly. Share this post Link to post Share on other sites
gerg 10,871 Posted January 20, 2015 Yeah that actually would be a step back from a Redline by the looks of it. I dunno what they were thinking when they designed it, probably would be a very slight advantage over the (very average) stock weber one. Still, going onto an XD, it would be replacing a single strommy, so anything would be better than that Share this post Link to post Share on other sites
SLO247 1,713 Posted January 20, 2015 Would it be worth getting the die grinder in the mouth there? If its better than the Stromberg and manifold I'll use it, I already have it. Or should I go the weber? I have a manifold but no Weber, had a mint one but sold it... Thanks for the info. Share this post Link to post Share on other sites
gerg 10,871 Posted January 20, 2015 If you've got a Dremel or die grinder, first thing you could do is tidy up the entry into the runners from the plenum. Air doesnt like sharp edges like that, so just put a nice little radius on each entry. Perhaps you could take a bit out of the short turn into 1 &6 to reduce the restriction. Anything more than that will require opening it up and porting out the guts, re-profiling some of the runner mouths and maybe even cutting out some corners and welding in some rounded sections. That's getting pretty involved and will be more trouble than it's worth. Share this post Link to post Share on other sites

matt_lamb_160 252 Posted January 20, 2015 No worse than a stock mani. If you are just changing the carb and the exhaust I would use it. Easy to swap to a Redline when one comes up cheap on eBay. Share this post Link to post Share on other sites
ando76 4,354 Posted January 20, 2015 D shape the top of that plenum and then hold on. I think this manifold will work and I would not be touching 1 or 6 at all due to their dominance in the runner. If there is a sharp edge in the entry to 2,3,4,&5 remove it on the high speed side (the top in plain speak) and on the inside of the runner. That manifold is so close to my 'Ray Hall - Cairns' 2 barrell manifold it is not funny. Ray is not a dill let me tell you that straight up. If his name is on it, I reckon it will work way better than stock. In reality it probably will not hold a candle to the new aussiespeed design - but hey you have it - so why not try it - what is the worse that can happen? 1 matt_lamb_160 reacted to this Share this post Link to post Share on other sites
SLO247 1,713 Posted January 20, 2015 Good info Ando thanks. I will do that. I've never touched anything with the rotary tool, just a normal grinding stone? I too have heard good things of the Ray Hall stuff so its promising to hear. Just weird I've never seen another one of these. I think I paid $50 for it, surely can't lose for that.

SLO247 1,713 Posted January 20, 2015 I have a linkage setup to suit a redline manifold. Should work or be close to working. Share this post Link to post Share on other sites

I see what you're saying Ando about 1 & 6 but i just look at those tight turns and shake my head. If the insides of those long sections resemble the outside, it would sort of act like a bit of a plenum as well as a runner, so i get why you say it would be dominant. My old red motor marine manifold had similar issues and after i opened up the inside radius on each runner (especially on the end cylinders) it gained 4kts top speed and was much smoother and torquier getting there. Agreed, got nothing to lose by fitting it, except maybe fuel economy with the Holley. Share this post Link to post Share on other sites
SLO247 1,713 Posted January 20, 2015 All good info, really appreciate it. I'll put this all into practice when I go to fit it. Just got sick of wondering about it so thought id ask. Economy isn't a concern as its only going to be a weekender. Share this post Link to post Share on other sites
Clevo120Y 815 Posted January 20, 2015 I would put a modified stock manifold in front of that, the air/fuel would shear off the short turns into the runners something cronic. But like the other guys have said, you got it so you may as well try it. 1 slydog reacted to this Share this post Link to post Share on other sites
ando76 4,354 Posted January 20, 2015 Once he D shapes that plenum entry to the runner and smooths the transition I reckon it will be okay. I have seem some stupidly ugly, home built manifolds perform way better than you expect them to. Gotta be worth a try at least... 1 Clevo120Y reacted to this Share this post Link to post Share on other sites
Clevo120Y 815 Posted January 21, 2015 Definitely worth a try for sure. Share this post Link to post Share on other sites
slydog 7,873 Posted January 21, 2015 I support the vote of no confidence on this unit...had a Ray Hall unit that looked just like it and it was no improvement over stock TBH. Then I went to a Cain 4 Barrel and all of the sudden it came alive 2 Clevo120Y and wagoon reacted to this Share this post Link to post Share on other sites
ando76 4,354 Posted January 21, 2015 That's interesting Rob - I must ask Ray about it next time I'm over there. The Ray Hall one I have has a divided (two hole) plenum and the holes taper into the manifold but it could still do with a bit of tickle around the runner entries. I'll do that before I send it down to Ryan for testing on 'Patches'. For $50 its gotta be worth a go at least. Agreed on the four barrel bringing them alive. 1 Clevo120Y reacted to this Share this post Link to post Share on other sites
