I know this is a stretch to actually ask a technical question, but does anyone have any idea of were to get some manley exhaust valves? Specifically the 37.5mm part number 11631-8? I need them YESTERDAY. I can get a set custom fabbed by SI to spec but it will take 2-3 weeks and I'm looking for faster.

Manley is backordered till god knows when and I have already tried over a dozen places. Any feedback would be greatly appreciated. Please don't ask me right now what exhaust valves are or what the are for or what they flippin do, just info on where to get them would be REALLY appreciated.

I have bought Manley Race-Flos from Summit Racing before. I don't know if they have the part you need, but you might try them.

hey mark!
try:
SHM,bill mitchell,summit,jegs,doug herbert mail order,mod max,anderson ford motorsport,or maybe al @ boss 330.
also if you can't find manley's i have used ferrea valves and connecting rods and they are first class products. i know for a fact ferrea makes valves to fit our engines from some artvicle i read a few months ago....heck it might have been about justin's engine. i'll do some serching also to see what i can find.

Yea, I know you didn't want Q's or opinions. But...I heard Manley isn't Manley anymore. I heard the name got sold and the new stuff wasn't the same as we are used too.

Try summit racing. Their service is top knotch. Also look into ferrea, they make nice valves as well. Just watch the overall length, sometimes these manufactures play with that to change the geometry for high lift cams, etc.

THANKS GUYS! for all your quick comments. The manley valves have been tried and tested on livernoise's own car making over 750 hp so that's why I was focused on manleys. I know of other valves out or in the works, but there was no test data on them at my hp levels to compare their effeciency. The fact I am stroked makes me even more at risk for valve float so I want something proven at 700+ on the S197 and the manleys are it right now. If any of you are doing rebuilds, start looking for valves now cause they are in short supply and large demand.

The intakes are only 1mm larger than sotck but it is the exhaust I am more concerned about anyway with the amount of heat I'm going to be producing at 18 psi. (that's before N2O) The Manley exhaust valves are 37.5mm opposed to the stock 34mm.

I have to give a great big thank you and 'shout out' to JDM engineering. Jim and Jim Jr. busted their butts to get me a set overnighte tomorrow and although they could have charged me more cause I was willing to pay, they only charged the manley list price. The guys went out of their way for me and bear in mind I have never spent a single dollar with JDM before.

I would recommend them in a heartbeat. They may not be the cheapest in town, but you'd be hard pressed to find better service anywhere else.

You rock, Jim![sm=icon_rock.gif]
