MY 375ci SBO

[olds307 and 403]

There is a guy running similar specs, I believe stock Edelbrock's running high 10's in a 87 442. What trans and rear end? What rad are you running? I need to get my 403 pulled, my stroker build will happen eventually, I want it done right. I am stripping my 94 4x4 with the Olds 350. Taking the TBI out and putting it in the Cutlass. Getting a 700 cfm bored TB and may even use the 4L60E. Just need to figure a cheap effective way to refresh the 350. The 307 heads make decent compression easy but don't flow. I also have #8's and 4A heads, may use the 2" intake in the #8's, bowl work and Speed Pro standard forged flat tops. I think the low cranking compression is why my car was slow. Shooting for 180 psi this time. I want low 9's in the 1/8 with this temporary motor. A LS makes way more sense. 6 bolt mains and factory heads that flow 320 cfm go a long way. The sbc doesn't have any advantage over a SBO except plentiful and cheaper parts.

Running a PACT 200-4r.
Don't know the stall yet but probably 3200ish.
The original 8.5 10 bolt, with Auburn posi, moser axels, and right now 4.10 gears.

Curious to see how the 2004r holds up. I have bought parts from them, was good prices and quality parts. What radiator? I am considering the Griffin dominator when I do the 424 ci stroker. My Champion 3 core will be fine with the 350 build.

Ya, I'll see. They say its rated for 600hp.
I'm running a aluminum Be Cool radiator, dual electric fans, CSR electric water pump, and BTR 4 corner cooling "thingy" off the water neck to the back of the intake manifold.

If you can get your suspension dialed in, you should have no trouble getting to 10's. Good luck, its a kick *ss project, and with small cubes no less!

Hopefully with all these goodies I can hook up, with the help of my slicks.
I also have Moroso Trick springs for front and rear, 90/10 drag shocks for the front, and 50/50's for the rear(not in the picture); and I'd drop my front sway bar and put some air in the rear bags for the rear coil springs on my track days.
Also not pictured is my rear disc brake conversion.

That is one nice bullet,did you assemble the engine yourself?

Sure did.
When the car is finally done, the only things that I didn't do myself is the machine work on the engine, interior, and the paint.

When is the dyno day? I'm courious too what a difference 12.5:1, cnc ported edelbrock heads, victor intake, and roller cam make over my 92oct 456hp/450tq 9:71, steel head, rpm intake, hyd cam SBO build. I'd think 550-600hp should be possible.

Spring I hope. It will be a chassis dyno, not pulling the car apart again....
I'm shooting for 550ish tq and 500ish hp (flywheel not rear wheel).
