SPE's 7.3 on the Dyno

psduser1 · Oct 18, 2014

Stock cam? Any port work on the heads, besides orings?

Good luck with that ATS 4R100. I wasted $5K on one.

Awesome numbers, though.

It's a Stock cam with no port work. So far the Ats is holding the power if it burns up will just build one.

Nice numbers on stock castings!

Plans to take it to the track?

Very nice!!

I second the track plans.

The s474 needs rebuilt and we're going to tweak the tune a little hoping for around 825-850hp on fuel. Were trying to get the truck to the track before they close.

Awesome work guys. Gives me hope for mine pretty comparable setups

Looks like your reg. return system uses hard lines? Any more pics?

What he said, impressive!

Girdle or hardblok?

Great job guys!

The headers and up-pipe system, is that a one-off job you did for his truck or is it something you sell? Thanks

SPE made the up pipes, Blown Away Enterprises makes the headers, Diesel Innovations resells them, and SPE modified them with V-bands (which looks like a great design)

I'm curious, why'd you guys stick with stock heads and cam?

Strokin572 · Oct 20, 2014

Awesome work! Love watching old dinosaurs putting down big numbers

This motor isn't hard blocked or girdled. We actually just removed the s475 billet off this truck and installed a s483 billet with a race cover. If anyone is interested in the s475 billet let us know we're rebuilding it and it will be for sale for a good price. Anything you guys are interested in just give us a call at the shop and we can figure something out for you.

That's more like it!

Why no girdle? Block flex and main cap walk is a known issue with 7.3s

Also why stick with stock heads and cam on a full build like this?
