537ci Really Sic Pak Wedge with Trick Flow Heads

[Hemirunner]

It's gonna make torque with those cubes and stroke. Big hydraulic roller? Hmmm. I would think it will go over or close to 650 torque. Hp should be a bit better than that. It will be interesting to say the least.

Everything I know points to 680hp/650tq so I guess we'll see if I really know anything at all.

Any more build details, head flow, valve size, valve-train/rockers, camshaft spec's, intended header tube size, whose rods, pistons, bearings & rings, what all's been done to the carbs, any specifics would be nice, was the intake matched, ported/flowed ?

inquiring minds need to know...LOL

 

[Hemirunner]

2.19/1.74 valves. Heads are as machined. I found the same tight guides that Jim did and opened them up with the hone. I cleaned them all and shimmed the springs to get close to Comps ideal specs for seat and open pressure. Head flow is on the trick flow site. The rockers are Crane gold 1.5's that the owner already had so we were locked in there. Would love to have had 1.7 on this. With the slots in the heads, they'll easily take 1.6 without issue and possibly 1.7 with minor clearancing. The rods are RPM 6.800 H-beams and it all spins on Clevite 2233 mains and 743HND rods bearings. We went with a Diamond 24cc shelf piston that I had changed to a 1.66 CH as the owner didn't want ring support rails or a floppy little piston as we do need durability. I mentioned the ring pack.
The carbs are set up the promax metering blocks and jet plates. It'll be an interesting day at the dyno for sure.

My 440 with trick flows, stock style 6 bbl, & trick flows made 590 with a mild solid roller..... I think it'll be closer to 700 than 600.

 

[dla4567]

Possibly, but that would be somewhat disappointing lol

Our goal is to do a complete 360 and land back on the wheels lol

Not trying to be insulting, that's just a wildly uneducated guess. I would love to see it go over 700. It looks great and makes me want to start a new build, I just ran out of cars to put engines in. Good luck and keep us posted on the results.

I don't get insulted easily nor did I read that as insulting. I would love to have had the max wedge versions and hog out the manifold, add 1.7 rockers and a big solid roller, but we are building a street car here

I'll look forward to see the results...
thanks

More cow bell.... I mean your going too need more center carb and total airflow too support the cubes, I don't think the stock sixpack's 930cfm it going too cut it or make you happy... Start looking for a 500cfm center(4412) and swap out the throttle shaft or one of those tweeked out outlaw roundy round carbs and swap the throttle shaft.. Your going too also need too trim the carbs air cleaner base too clear the rear fuel bowl and too keep it looking like or close too a Mopar looking set up.

Then hold on......And make sure you have a change of shorts..

We had time to make a few pulls today. I set the timing at 31 to start and it ripped off 660hp on the first pull to 6000 rpm. We pulled it up to 6500 and it belted out 674.9 hp and 700ft/lbs. Not bad for zero tuning.

 

[Wookie316]

Those are impressive numbers. Hope to see a video.

 

[dla4567]

WOW, that is very cool!

Great Caesar's Ghost. NICE!!!

 

[Hemirunner]

We added timing one degree at a time up to 35 and lost a little power. We set it back to 31. Fuel was 67 on the center and 88's in the outboard carbs. We had to rig the linkage to open all carbs at once due to a lack of ported vacuum at the carbs. I'm guessing the metering block in them was to be used with some sort of progressive lonkage. I need more six pack tuning experience for sure but what a pain to work on lol.

I have everything but the heads, to do a similar motor. Just nothing to put it in. You're tempting me....DAMN IT!!!

 

[Hemirunner]

I would like to do a similar combo with the max wedge port 270cc heads coming out later. The bigger heads on 537 cubes with the matching trick flow intake would be a killer.

Do you have that same intake?

 

[Hemirunner]

Cam in this was a hydraulic roller, 260/262 at .050 with .650 lift ground on a 112LSA. Valve spring pressure was 170# seat and 460# open. Comp custom with comp lifters and smith brothers pushrods.

 

[mmissile]

Do you have that same intake?

Yes sir.

 

[Canyon707]

who makes that intake?????

 

[Hemirunner]

who makes that intake?????

Originally, it was made by weiand for Direct Connection and carries a mopar part number. It was only offered through DC for a short time and haven't been made since.
