TH350 or Powerglide?

[Zack]

Car will be alot quicker with the PG.....

That is my hope. Dropped off the PG for rebuild, shift kit and 2000-2200 stall today. Will be ready to pick up Friday. I am sure it will serve my needs perfectly.

I'f I were to build mine all over again... I'd do a 700R4 to get overdrive... with 1to1 and 4:11 rearend... you'll be spinning driving down the freeway! (guessing about 3300+ RPM)

I don't really agree that it would be quicker with a 'glide, I think that little 283 would make use of the lower first gear to get it moving. Glides work well in light, high HP cars eg: big block Altereds and dragsters.

Glides take a lot less HP to run them. That is why they are so popular in drag cars. It is also amazing how much HP they can stand.

I forgot to tell you all. I dumped the 283 for a built 350. It is pushing between 425-450 HP. Here are some of the specs on the engine:

This setup with the PG and it should scream. I will be picking it up tomorrow.

Looks like a good engine. 2 things you may have trouble with. The 2 pc chrome timing covers, most of them leak oil. The 1965 double hump heads do not have bolt holes in the end to mount the alternator if it has a long pump and pulleys.

Timing cover is the first piece to go and i will be mounting the alternator directly off the lower drivers side of the block. I have to build an adjustment bracket for it but it will work great there and be down inside the frame. Dad did his that way and worked out very nice. :good:

Yeah, never had any luck with the chrome timing covers or the chrome water necks= pita

What is a Altered but a really hopped up T with all the NHRA inspec's done and a tube chassis. A T is a Econo-Altered, basically.
A situation with 2 identical T's running on the track:
1. Both cars launch hard, reving, the turbo 350 shifts into 2nd gear, while the PG winds 1st gear on out, goes into high gear.
2. While that TH-350 is winding out in 2nd gear getting ready to hit on 3rd, the pg is winding out going thru the traps.

A turbo 350 has that 2nd gear to get all that weight moving, keeping the engine rpms up, but with a light car, it isn't needed. if your prefer it, be all means. I prefer to win races....

Thanks, I am hoping with the light weight of this bucket it will get up and move on pretty quickly.

Yea Ron, I remember back in the late 60's and early 70's, you couldn't give a powerglide away! Nobody wanted them because nobody could get them to hold together. Once they got those bugs worked out though, holy crap! Hahaha.....

Roger on that Mike, I'm running some anomalizing software on this thing, sometimes folks think I'm from overseas.....I'll just post a link next time.
