Going to put a 202 Holden / trimatic in this slug to enable me to enjoy driving... has anyone here done this that can help with details. I have a reasonable grasp on it but it doesn't hurt to ask. I have engine and gbox ready to go so have measured everything and it look good ...apart from enthusiasm. Haven't been able to find a helpful site here in OZ either.... Thanks
202 Holden and Trimatic are Australia only. A 202 is a miniature version of a 235 and a Trimatic is basically a three speed Powerglide built by ASIN.
Missing information: Is the rear end stock? You are swapping an I6 for an I6 (which is probably smaller) Is it 12 volt converted? Stock column? If so are you going to adapt that to shift the transmission? What exactly do you want to know? BTW, I know nothing about GM stuff, Holden or otherwise, but it sounds pretty basic. There should be plenty of people to reach out to on the central coast. Although the only people I could nominate do it for a living.
Your Chev has a torque tube rear end, fitting a 202 Holden and trimatic will need a driveshaft and another diff.. You'll still have a slug tho.. Find a Chev 250 and fit that, do some research here on the HAMB, you might find it'll be close to a bolt in fit..
Ummm..... No...... I don't think so. The earlier Holden "grey motor" was based on a pre-World War 2 Buick inline 6. The "red motor" was a design all of it's own, and this includes the 202. And I have never heard of the Trimatic three speed automatic transmission being related to the Powerglide. I believe it was a GM designed box, the TH180, and was predominantly used in the European market....
I would think the little 202 would be a bit under powered in such a heavy vehicle. You could try and chase up a 292 chev 6. A letter chev 235 with twin carbs and duel exhaust would also be very cool. A 3 speed manual with electric overdrive would make it a nice hiway cruiser.
The red Holden 6 is just a smaller version of the chev 250 6cyl. It looks identical except the distributor is in a different spot. The trimatic was a very weak transmission.
I'm not going to buy into this but, this specific subject has been thrashed out before. I think in the last 2 years.
Mate I'm all for using what you have but Holden six and traumatic, do yourself a favour find a blue flame and glide as well as a open drive diff and away you go , even a falcon six and auto be for power
I've used Holden sixes all my life in different projects but in lighter vehicles than this. I'd use a 253 red with Trimatic if you only want 2 pedals. If you're not going to flog it on the 'strip the Trimatic would take it. Easier to procure and easier to get parts than a blue flame over here.
There are a couple of chev 6’s on fb at the moment. Having said that a 250 6 out of a falcon wouldn’t be bad. + auto.
I did this with a '51 Chevy. It was a dramatic improvement in performance and drivability. Simply putting dual carbs on your 216 would probably be a big improvement, too. Dual exhaust would help. The automatic is killing your performance and making it feel like a slug.
