GLWTS, it sounds like a fun car.

The engine sounds a lot like my plans for one I want to build soon. Let me know how that thing is versus a stock level of compression and smaller heads, TB etc.

Does that need 30lbs injectors, wouldn't 24's do fine for under 6000rpm? I'm aiming for the 10:1 range, with a ported GT40 intake, and a similar head if I can find them. I'm hoping that's worth an extra 50rwhp over stock.

I think you have a good plan for a good car.

It's a joke.  The Corral is a web site.

Like Nate said it's a tongue in cheek thing. The low RPM torque crowd over there get all sideways if anyone recommends anything out of their perceived norm for a 306. This engine has all their requisites of what is enough for a 306, TMoss intake, Ed cam, AFR 165's 1 5/8 longtubes. The 75MM TB and 3" exhaust are a little out of place, but they're what I had.
BTW, none of this should be construed as flicking boogers at Ed or TMoss, they both do great work, if I thought it was anything less I'd have sold those parts and got something else.

If my shit doesn't run...
I guess I'll have to concede to Corral, and stop posting here.

That's a great combination of mild and slightly over, parts. It will run great, but I think the big compression bump will add more power than the rest; it's a nice compliment.

The bump in compression helped, the 1.72 rockers helped, I think, having the right spring installed height helped, reciprocating assy. balanced helped, 75MM TB and 95MM Mass air probably helped and the tune helped some too, I think. It made 333@ 5400 368 @ about 4200 on a dynocom dyno. I forgot to get the electronic versions, I just have the printout. Tried spark from 34 to 35 at WOT no change, and leaned fuel to 12.3 and it didn't pick up anything so pretty much had it dialed in from the start.
I'll post the dyno sheet once my son scans and emails it to me.

Correction to the above it's 364 RWTQ, not 368, my bad.

David, how much were you considering selling it for?

Not sure yet, kind of depends on what I've got to do to it get it finished. I may paint the whole car yet, and may change the wheels out too.
This is the only pic I have of it...

I won't sell it until he comes back for Christmas break, I'll let him drive it to make sure he wants to sell this and keep the sport trac up there in Ohio.
This seems pretty typical of similar builds that I've seen on corral with these parts. I was surprised at the torque and power. I was expecting 310HP/340TQ or thereabouts.

Thanks bud! :smile
