Smartest thing you could do is to give Cliff Ruggles a pm on here.
Bought several converters from him and every one was dead nutz on the money! He knows what he’s doing. Blindingly fast shipping also. |

I am running that cam ! Just FYI you need compression for that cam and I'm zero decked running 10.75 to1 461 edelbrock heads with 1.52 rockers. I had Coan engineering in Indiana make me one in early 2022 coa-20211-4 and I love it. Stock tires 225/70/14 on the rear and it burns them off when i get into it. It has the original 10 bolt safe-t-track but I have the small tire so them break free to not stress the rear too much.

Good converter = $800
Okay budget converter = $300 - $400 So that leaves out a custom converter from Cliff. Your best bet on a budget would likely be something along the lines of a Hughes GM25. For myself I always spend the money for a quality custom converter. Your driving pleasure and satisfaction should matter enough to spend a little more rather than regret buying cheaper and never being truly happy.

Thanks bman. I understand, but unfortunately some house holds especially in this economy don’t have thousands at a time to put into a project. Some do need to do what is affordable and not the very best so we can still enjoy the hobby.
I do appreciate the info !!

You would do well to pm cliff…
His converters he sells are very competitively priced. Add to that the fact that they work first time out of the box like their supposed to, for a Pontiac engine, that saves time and aggravation having to pull the damn thing back out a second time because the converter builder “oopsed” the first time…. That alone is worth $$$. We’ve used quite a few manufacturers at work for quite a few projects, and the only 3 that did what they were bought to do …came from Cliff. Not saying I’m trying to be a paid shill advertisement for him, I’m just saying the stuff flat works like advertised. No more, no less. |

I agree with Bob and Bart.
One of the biggest "bangs" for the buck is a custom torque converter made specifically for your combination. Another point is that, Pontiac converters need different properties than the Chevrolet World stuff does. Save up, if you have to!!! Have fun with that cool car, in the "Shire!!! Jeff

why not try the B&M you have. The description in The B&M catalog closely matches your engine specs.

Call Lane at PTC and buy what he recommends. Or Cliff.
A converter is one place you do not want to cheap out. |

The 20412 B&M converter won’t work in the 200R4. It is for a TH350 or TH400.
200R4 has a lower first gear, doesn’t really require much of a stall with street tires, you could just run a stock converter if your on a budget. Reman is less than $150. |

Make sure the company that builds the 200-4R transmission knows what type of converter will be in use.... lock-up or non-lock up.
