Only 1 email over the weekend that I know of...ofcourse I'd be willing to build it.

Wow...man I'm really sad to hear of this. I know he was a christian though, so I feel good for him as he's no longer dealing with health issues and everything else we deal with. I will really miss him posting on here. Godspeed John!!

For the intended application you won't see anything really from a longer rod...less piston weight but heavier rod...short rod works well with pump gas and tends to be peppier throttle response. Just how I would do it from experience.

Better combo would be a 4" crank and 6.125 rod...more porting on the heads, and cam it 236-248 @.050 on a 108lca.

I gotta get going on block work...lifter bores are done.

Next year we should have sb mopar and bb mopar rockers available, 1.65 and 1.7 in both...rocker arm on shaft, oil thru cup adjuster, roller tip but non roller body. Good for hyd and solid FT, and hyd. roller up to around 480lbs. open pressure.

Love it! NO BS bullshitting comments, just fire it up and rev it! Cam sounds...pretty good ;-)

Better now...spent my weekend with the stomach flu. Always something...lol

Yep...water has no place being used to slow the flame front!

Would you take 300.00 WITH shipping to 92201?

Only person laughing would be the guy that's never picked up a grinder and gave it a go. I've learned from the most unassuming people at times!

2.08...the tube pulls air to that side of the bowl. If you want it there. I really don't think much of my advice will work with your valve job. But I do think laying back the chamber wall should get you some but maybe not until you move the ST belly back some and blend the VJ on that side.

Here's a shot of removing the bolt buldge, tubing so you can still oil the rockers via the heads. This effectively pulls air over to that side of the port/bowl/chamber and allows a much better ST shape on that side. Those heads flowed good, around 310-315 cfm at .700 lift...

The pinch should really not hurt a port like this...even if it's a bit large. I really think it's the valve job/chamber hurting things. Still fun to see what the changes you make do. What's really fun is when you unlock or find what the port really likes. Then it's like magic and makes you...

Exactly...the belly of the ST + IMO the valve job and transition into the chamber + lack of area around the valve is causing problems the bolt bulge and pinch won't cure.

I don't do anything with the 38 top cut...just leave it 38 and hand shape the chamber wall...I only concave the area nearest the valve OD...then I taper the concave shape both towards the plug side and the opposite side more angled and less concave. The quench side needs attention more than...

Where the yellow is, it would help to lay this back to the gasket line, and concave the chamber wall from the deck to the seat top. I also don't do my seat cuts that way, but making more room for the valve will help...it will also speed up the air so that will make the pinch and ST more...

Dude you have to work the chamber wall, especially when you go to a larger valve! The pinch won't show you anything until you unlock seat area (bottom of the valve job to the deck).

20 years ago I read a post by Darin Morgan, I think on speedtalk where he said he never leaves a belly on his short turn. This really got to me, and at the time I was getting help with some of my porting from Larry Meaux. I would send him photos, air speed data, and area at particular points...

The chamber wall is, in reality much taller than your drawing...if you do it right (chamber shape from the seat to the deck) the bore intrusion is no big deal honestly and it does make more power than keeping it tight like say a 4.080 gasket bore. I don't do this as much now as I've learned how...

Yes so far I've not touched it to get that power...I've also not build anything crazy with them...i.e. solid roller, high compression, etc...but I feel removing it using E85 may be proper...hopefully. I would love to try it but so far the power has been good leaving it in.

Minimum dur. @ .050 on intake around 254@ .050.

So far I've left the vane in, but if I ever do an E85 engine with them, I'll remove it.

I know for us, when we build a 408 hyd. roller deal, pump gas, I have to make changes to the intake porting on the TF head if we want more than 540HP. Those changes allow 575+ at a real 10.6:1 compression! And the port doesn't really end up flowing much more air...you have to remember the...

I would do a compression test to try and figure the compression before I ordered a cam, but I can tell you if the heads are not ported, it'll be slow. Also headers are too small for W2 engine, and the dual plane...big time power loss! I would install low gear set in the trans before changing...

Is that corrected HP or uncorrected?

We've made just under 580HP with them, using a hyd. roller cam! But they need work, they were not ootb heads at all. Compression was 10.7:1.
