My opinion is that’s way too much cam for a heavy truck.

Let’s see how many responses I get. I already have an advantage over summit as I don’t have to charge tax due to my low volume.

Since the intake is only flowing air not fuel, the single plane intake is not as much of an issue as it is when it’s wet.

PM me if a group of people want this system. I can help with fuel systems too.

Does anyone have real world experience with the Edelbrock Pro Flo 4 Injection kit? I ran the Fitech kit for 2 years and after working out initial bugs from Fitech's too fast to market glitches, it was pretty good. However, after an issue with the ECU that turned out to be warranteed, I sold the...

yes. .040 360.

My ported eddies went 505/526 with a mild hyd roller -230/243 duration at .050. Need to consider cam choice as well.

Ive been running these heads since the first year they came out. I ran Crane golds first time around. Then switched to Comp steel magums. Last rebuild - 2yrs ago we milled the pockets to improve the geometry. No matter what rocker you run, you MUST MUST MUST check the sweep over the valve tip...

Secondaries?

Stock mounts and a torque strap from schumacher. It has urethane on one side for dampening and is adjustable. Simple and effective. Super smooth too.

Agreed. Too much timing. Back off first then see if the plug is still overheating.

Comp cams. 10+ yrs and 2 motors.

My stroker liked 30 deg too, 11.3 ported eddys. I make the same tq with hyd roller 230/243 and a dual plane.

I would run an 18" case muffler of which there are only a few on the market.

Depends on what valve covers. Harlands hit the factory baffles. I run Comp Pro Magnum steel. They seem more durable than the alum parts.

I agree Milodon is a company in the dark ages...But, my road race pan is pretty trick. I modified it to accept a 1 piece silicone gasket, and it is dry and provides good oil control on the road course.

I bought a Kevco pan once and returned it. It looked like a kindergartener welded it. Hope they are better now. Milodon makes nice stock depth road race style pans with excellent oil control.

Nobody mentioned a coolant tester. Pressurize the cooling system while its cold and listen carefully.

Lash caps seem to be a band aid. On my eddies we had to mill the shaft pockets to drop the shaft down a bit. If you need to raise the shaft they make spacers.

Absolutely correct here. I haven't seen an aftermarket cover yet with any real baffling. Look inside a factory cover and duplicate.

I've been using all stock valve covers, breather and pcv on my 11.5:1 stroker with no issues. Even on the track the setup works. If you look at the size of the OE baffles vs. the junk in aftermarket valve covers you'll see. You can always put a can in between the

If you have properly baffled valve covers (most don't unless they are stock) the pcv and a breather work fine. I run all the factory stuff on my stroker and even on the road course no issues.

I run a dual plane on mine 236/243, ported eddys and 11.5. I know IMM has lots of time in the dyno room, so I'd listen to his suggestions.

I think if you used a Saginaw pump it may be closer? Since its a press on pulley, maybe pull it slightly?

11.3 comp, 230/243 custom hyd roller from IMM. Cracked 500 hp easy on the dyno.

I would think that lift is a little low. What heads? I run a 230/243 split on a 112 in mine, made 505hp and 526tq on the dyno.

What makes you think its the motor? 260 high energy cam is mild. Most cams dot to dot run fine too. Possibly a trans issue?

I'm a Joe Gibbs dealer.

If the heads aren't really ported I'd stick with a cam below 250 duration. I went down to a hyd roller and picked up power. I'm basically the same as you, 11.5 compression, RPM intake, but with ported eddies and big valves and a cam that's 236/243. Motor made 505/526 easy
