Total street car but was run with no exhaust today.

10 seconds here we come!!

Knocking on the door! It will happen!!.

Nice!

Good to see the 350P being done.

go 350 go !

Very impressive. The mph looks a little low for the time.

I think its spot on.

Still tuning. Only 2nd time to the track🙂

Congrats! Definitely a well thought out 350. Nice job. I'll be watching for the updates. I'm sure you will get there.

I run a 10.80 with that MPH. He is doing fine.
Get the 60' down and you are in the 10s.

Impressive showing for the Rodney Dangerfield engine of the Pontiac family. Easily a 10sec car with a better 60' as Dcar said..

agree very nice combo. what rods and rpm are you spinning it to?

Eagle H-beams. Shifting at 6400. Currently through the traps at about 6200

Why are you shifting so low? Your peak HP is at 6500. I think you are leaving .1 to .15 et decrease on the table by not shifting at around 6900.

We went back to the PP dual plane....its .07 quicker in 60ft than the Victor. With that manifold peak hp was 6200. I still agree it wants shifted higher....this is only our 2nd time out with it and it got put right into bracket duty after one T&T day. Lots of tuning and tweaking to do. Lining up another converter to try also. Its deadly consistent already. Firm believer in efficiency=consistency.

You engine might like a smaller single plane intake. T2 or Tomahawk. The Warrior was designed for a 366ci engine, but hard to find and expensive.
The Victor is simply too large a intake for a 350. But you have a race engine with a big .670 cam and that usually means the right single plane intake.
Tomahawks are cheap and work well.

You may be correct but my dual plane isnt really normal. LOL. Within 15hp of the Victor at peak and a MUCH better torque curve than any of the single planes. Destroyed an out of the box RPM(it was RAIV matched) by 30+hp and 10lbs. I have a ton of time on the flow bench getting the runners equaled both in sq/in and flow as best as possible.🙂

Good job! Nice build.

Sweet motor! Wanting to do similar.

Sounds like you have this thing dialed in.

I threw away a perfect 1969 350 std bore block with the factory valve reliefs years ago. Even those things are going for some money these days.

Be happy to guide ya any way I can.

We are currently working on a 670 headed 350 build for my son's Ventura

Nice! What size tires do you have in the back? How’s your traction off the line?

Back in the day I had a 67 GTO HO auto. car that I broke the motor in . I got a junkyard 350 motor in good shape . Switched all the HO stuff to it , Cam, Heads that had a little work, exhaust manifolds , intake with carb. , it was very impressive how well it ran..... It would still beat a Roadrunner

I’m working on my 350 as well.. gonna be putting all this on her soon. Just got the CNC heads back from Butler and the intake from Wilson. They do such beautiful work!!

275/60. Mickey T. SS tires. Hooks perfect. We have used the tires in the 9s on other builds

Nice!
