some 370I / 250E KRE D-port cylinder heads.

Chamber and port magic performed by none other than my good friend Dan Barton of Westside Machine here in Houston.

Dan ordered the heads from KRE semi-finished - sans guides, seats and pushrod holes.

These heads are going on another good friend's (Walter Lansing) new engine for his '64 Tempest.

More details to follow, Walter's car is gonna FLY!

Those are some impressive flow numbers. Good luck on the rest of the motor. Keep us posted.

[Lloyd-TX]

five more pics . . .

Valve sizes are 2.200 and 1.660 IIRC.

Flow numbers are @ 28", .700" lift on a calibrated Superflow bench on a 4.185" bore. Walter is running header adapter plates and 2" primary headers. Dan Barton ported Victor intake.

not sure but it looks as though he took a little too much meat out of the two exhaust ports on the first pic, on the first set of pics

Nope.

That's why you can see he threaded two aluminum bolts in the stock location bolt holes and re-surfaced them flush. He's going to be drilling and tapping new holes further apart and corresponding wider new holes in the header adapter plates.

I think he means inside the port, not the header flange.

Lloyd-

Do you have the entire flow sheet?
What comb chamber size?
Solid roller?

[pro-tour79]

poped into the ext. bolt hole, no big deal happens all the time if anything press in a sleeve

[Walter Lansing]

Lloyd,
You b@st@rd how dare you handle my heads before I get to see them....ha ha

Pon jon, I think they started as 85 but the chambers were larger than the bore so had to be welded and reshaped. The cam is a solid roller 276/274 735.

[tstevea]

Looks like to much was taken out!Looks like he epoxied the intake side.To much meat taken for my taste

[JKrull66]

Walter,
looks like your stepping up to the next level, >Pilot< ... Good luck, it ought to fly. All it takes at cubic dollars !!! Be putting on airfoils next... May-bee they won't notice it on the runway... get a few runs in at the shop.

Rumor has it that Dan has gotten 430cfm out of KRE HP heads also .

[Walter Lansing]

HMMMMMM................ I wonder who's head that is............... I head about that!!!!!!!

[goquick]

The 2" primary headers is going to cost you 20-30 hp. Step the size up to at least 2 1/8". A step header would be a help too. That is great flow numbers on the intake. Mine were 340-343. My exhaust is 248 but with stock bolt locations.

At what flow numbers do you consider 2 1/8"?

Ponjohn for me displacement/rpm range has been what seemed to matter. A small cam 350/400 does ok with 1 5/8 . basic street perf cam on a 400 1 3/4 does ok 455 street perf cam1 7/8 fine Step up to Race and 1 7/8 for the 400 2" for a 455 become minimums (if your not a tractor motor setup like Jim hands deal) I would want at least a 2.25 minimum on a 505.

Just an opinion but if using flow as a guide I would use the intake flow. (more in more needs to go out) I think most of us have seen the flow bench differences on exhaust between pipe and no pipe extension. Dont need your exhaust actin like a govenor.

Wonder if anyones got a guesstimator already worked out based on flow numbers?

[Daniel Barton]

The epoxy in the intake port is to fill in the void behind the guide to stop fluidic switching and to repair a dip in the intake floor that each port has... it could have been polished and the dip left in there but I didnt care for the imperfection in the casting, the head had some core shift and that is why it broke though in the one exhaust port. The camshaft is a 267-276 @ .050 solid roller .735 intake lift with a 1.7 rocker and .695 lift with a 1.6 on the exhaust.

[J.C.you]

that is a very nice set of heads. biased port floors, i see the pro stock trick in the bowl too...., is that a 50* seat?

[Skip Fix]

Dan did a little massaging on the E heads going on my 500" project. Hopefully to be finished and maybe dynoed by the end of the year.

[Bill Bolin]

Any more info? What is the runner volume? What are the low lift #'s? Just curious about the velocity.
