Wonder if it will clear, and if anyone has any results? I have searched for a couple hours, so checking. Plan to throw a carb on it for now, and rocking out.

i was told by tsp that the cam would work in the lq9 long block. i got the ms4 patriot dual springs and 7.425 pushrods that im throwing in my lq9 swapped 98z next month after it goes through inspection

Let us know how it works out, I've been wondering the same thing

it fits fine in a stock ls1 (68cc head) and the lq series uses 72 cc heads. you'd have miles of clearance.

u are good u have a 72cc head and i have ran that cam with a stock motor with 64cc heads

I am not an authority on LS heads, but I was not aware that the extra chamber volume on the 317 heads was achieved by a taller chamber with a higher valve location than the ls1 heads. I thought the difference in volume was due to a more open chamber and the valves were in the same location. Could any one clear this up?

Thanks again,

That's correct. The volume of the chamber is not what determines the valve drop.

Thanks for the clarification. Seeing that you're representing the cam manufacturer it'd be great to know if you guys have ever attempted this same combination, as in a completely stock LQ9 long block with untouched heads and a stock thickness heads gasket. If so what kind of ptv did you find and what kind of power did it make? If you have not had direct experience with this configuration what ptv would you expect to see and what kind of flywheel hp would you think is possible given a victor jr intake, carb, and long tube headers? Thanks in advance for any input.

I'd atleast be ready to pull the heads anyway to mill them down alittle...even if it means valve relifes to get the compression up some... I don't see why it wouldn't drop right in, but why leave power potential on the table with the stock comp ratio

so a ms4 in a lq9 with L92 heads is to big?

Budget reasons. If I pull the heads, then I have to pay to have them milled, buy head bolts and gaskets, and either pay or buy tools to to notch the valves if it gets too close. I'm going to spray this engine so I'd rather not cut on the cast pistons if I don't have to. Plus, if the heads come off L92's are going back on, and if I did that I'd likely want to go ahead and put rods and pistons in it, and then the build starts getting more expensive. I just don't have the self control, I have an all or nothing personality! (but mostly a nothing budget ) Besides, 10:1 isnt too bad. I'd worry about it more if I had the LQ4

The 2.165 intake valve would leave you with less ptv than the 2.00 intake valve in the 317's

Lol you had me at budget, I completely understand...I'm on a tight one too

LOL, it's tough to be fast AND broke. My 10wk old daughter started daycare last week, $600/mo!! I knew it was coming, but it still knocked a big chunk out of my hot rod budget. Gotta take care of the little ones first

Your valve drop with the LQ9 & 317 castings will allow the MS4 to clear no problem

Thanks! I'll still check with some light weight springs but I just didn't want to buy a cam that was known to have clearance issues with my set up.

I like the combo. Any dyno time or track numbers with the combo?

You might want to think about upgrading your valve train. A LS2 timing chain and PRC springs with good pushrods might be good insurance. If your going to pull the heads you might just as well.....jeez.... here we go...............
