Re-read this. Do you see the plus symbols? 2500 and 9:1 are the bare minimum. You need more stall and more gear. That's what I would do.

Big cam, low compression, smog heads, high gears, low stall. It at least has the right intake manifold. Option 1. Go with a smaller cam. Talk to the cam grinder about building cylinder pressure up and working with flow limited heads. Option 2. Pit in a 3500 converter and 4.10 gears.

Surprising how strongly guys feel about alternators. Especially about oem style units. I'd never bother with one of those things unless it was a show car resto deal.

I can easily find my Toyota 4runner alternator in most Autozones lol... Duralast Alternator 14668

They're steel. And I second the high quality.

I think the 409 is pretty cool. Weird, yes, but cool. For similar reasons I also like other engines of the era. Ford FEs with the strange intake manifold that doubles as half of the valve cover gasket. Neato! Any of the Cleveland 4v headed engines. Super cool. Poly 318s are pretty cool...

That assumes 100% net profit margin... Unlikely

A 5 axis with tool changing capabilities is a 250k investment. You can buy a whole bunch of natty ice with 250k lol

Hopefully the heads flow as predicted I e. Around 290. Otherwise it doesn't offer much against the competition. I think afr released another Edelbrock copy recently and it's like Zzzzzz Zzzzzz Zzzzzz

I mean...as usual it depends. I'd mig and not think twice . Some people are super picky and tig everything so....

Unless you're doing something serious like a highly boosted application you should be fine with one. If you're not good with a welder you can just take the bung to an exhaust shop. Any half competent exhaust guy can add a bung to the collector. I love using an O2 sensor. Particularly helpful if...

If it's gonna start off in the 290cfm range, with a 2.08 valve... isn't that pretty capable as a starting point? Port them from there. An Edelbrock is what in the 250s stock? That's a big jump. It seems like it could get upwards of 600 HP with a bit of port work. That's pretty dang good for...

I personally love that it's using Chevy rockers. That opens up all kinds of options for very good rocker packages, price points etc. Lots of ratios available from mild to wild, different body materials, bearing packages, on and on. Shaft rockers are nice, not gonna argue that. But for what...

Agreed. As a business owner myself, battling to get every scrap of revenue possible, it's gotta make good business sense. If the only thing that your heads do is offer a good alternative and a great cost point to improve your crate engine offerings then that's a win in itself, and if anything...

That's awesome! I didn't realize. Are these already released?

Sales on the TF190s seem to be pretty good. Being a profitable business, I'm sure that BPE has to look at many things to bring something to market. What are the net profits on the investment is going to factor in hugely. I'm certain they know how to build a high performing head. The question...

For my next batch, would it be better to make the plate with a hole already cut out there?

Yep, that's me. It's in the parts for sale section.

He logs a bunch of data. He's monitoring wheel position to help with his shock tuning. That truck is very fast.

I love this guy's stuff: He's making mid 600's at the wheels. So 750ish crank in a sbe 5.9. Very impressive and makes me wonder-again-what the limits really are.

Nice. Ain't send cut send great? I have a Bambu carbon and that ***** awesome.

I studied fluid mechanics way back in college. Enjoyed it and did well at it. At one time I could apply Bernoulli without reference to a textbook. The main thing I recall about it, is that the basic assumption is that it requires smooth non varying flow. That doesn't describe the behavior of...

:lol:

It's always an exhaust leak right? Really.... it's not a Mopar if it doesn't have an exhaust leak or two snicking away

Poor man's stethoscope.... https://www.amazon.com/dp/B07F18V2X8?tag=fabo03-20 Times have changed. Buy a tool to get the job done. If you cant spare $5 you're in the wrong hobby. :poke:

You put it upside down on a flat surface and run it underneath a dial indicator and measure the crown.

Let me know how I can help. I have a couple business websites, I could set up a little download hosting link.

I'm really sorry man that's rough.

This is just a suggestion and I honestly have no idea how one would go about this. And I know there would be an element of timing here with family grieving etc. But PBRs passion (or one of his passions anyway) was porting the SBM heads, and sharing general information that you would discover in...

I loved PBRs posts. Such a stand-up guy. He'll be missed for sure.
