Maybe you've done too many things correctly

Evidently not enough :anitoof:

Maybe too much

In terms of bang for buck, it's a lot of money to end up with basically what you got now. How much more would a stroker crank cost? Couldn't be that much more ...

My thinking is, I'll have a new engine I shouldn't have to touch for another 20 years. And I don't expect to live that long

This.
-You write the check once and get nearly everything you wanted.
-You are already familiar with the TBI setup and layout.
-You have a relationship and person to go to if there are issues instead of junkyard or online retailer.

Money well spent.

Well, kinda I'm getting better flat top pistons for higher compression, moly rings, and 5 whole extra cubes.

Not much more for the crank, just the clearancing of the block and balancing. Then feeding it, my 46mm TB won't do it, I'll have to go to at least a 50mm from a 7.4L

I mean, if you're already dropping $4000, what's a throttle body? Or get yours punched out. Aren't you getting the 350 rotating assembly balanced?

I asked about that and haven't heard if he's gonna do more than the already balanced assy from Scat.

Another $500 or so. I know but, where do you draw the line? Originally all I wanted his to do was clean and assemble the short block, then I'd build it. For $1200 more, he wants to build it. Like I said, I understand his position about others sticking their hands into his build, then coming back at him because the engine failed.

That's worth some power. I guess I have sticker shock.

Getting something done right the first time is usually money well spent.

Aren't you close to Jake's performance? maybe give him a try?

Long story short my buddy is going to try a new internal harness, shift solenoids and the MPS before the trans comes out.

I think you are missing the fact your 46mm will feed it just fine. I have set up a 406 under the stock throttle body using the TBI heads. It was not a high reving engine at all. Made its power peak around 4500 rpm. However with the torque it made it easily outran a 350 Vortec turning more rpm. Torque not RPM is what moves a heavy vehicle.

With this cam (224/[email protected]), Comp Cams said its power curve is 2000 - 5500. My TC is 2500 stall so, I'm moving my curve up a little. Right now I have it shifting at 5000 and, once I get it dialed in better, I'm gonna try 5500, maybe higher, to see what happens when it shifts from 1 - 2, with the wide gearing gap the 700R4 has. Acording to TCI's calculator a 650 CFM (according to SPR Performace who built mine) is good to ~6000 RPM for a 355

Where with a 383 it's marginal

Then there's the question if my Edelbrock Performer 3704 TBI intake will flow enough too.

In a bigger engine the powerband of that cam will drop. Comp and others rate their "powerband" on a 350 with stock style heads. Cubic inches will decrease the powerband and head flow will increase it. The same cam in a 283 will be alot more radical than it is in a 400 and pull more rpm.
