Very interesting, I've got an M type Vauxhall 14/40 engine & g'box put aside for my T roadster project & had been thinking about a Bull Nose Cowley radiator. That Oxford one looks great, will be a very interesting addition
Nice to see you back on this. No idea how high you're intending revving it, but I get scared around 3,000 (60 mph in top) with my '28 chevy beach racer. Unless you're planning to go a lot higher, maybe weaker valve springs might give the rockers an easier time and also act as rev limiters.
It's a real balance isn't it! We recently put together an 20's French twin cam, valve Springs were very light - 40lbs valve open, we ended up with Carbon on the seats & valves not shutting after 50miles. We went to 95lbs, valve train worked as it should but the extra load was noticably higher.
Nowhere beyond 3000 for sure, above that is daft without pressure oiling @Outback whats this French Twin cam we need to hear about.
It is, but I've never noticed valve bounce or had any problems with my prehistoric stock springs which are pretty weak.
I have a huge jump up 2rd to top, I found a small low revs points activated rev counter so I could see when to ****** it into top, worth having or else I would never dare hang on to second for that long. My engine is stock and in need of refreshing, max power at 2,200 revs, but the soft sand just kills it if I change up then. I get the 3,000 revs being safe from this chart from the on line 1928 Chevy specs book.
If you are in the market to sell the 153, I would like to have first refusal. I put one in my '34 Ford in '72 and it was fun.
Still chipping away at i† and when it goes together it'll have the built 153, but I have been gathering parts & information for an early build. Just got a Genuine Chevrolet Parts book for four cylinder models from 1940 today. Good illustrations and information. Putting this one in a T is really cool.
Still got all the Chevy parts and Olds head, just had to put it into storage for a while as I had to go back into full time work.. hoping to get back on it soon
So glad you are still about, I understand how projects blow out or get put on the back burner. There's so many cool projects around here that just fall away. Looking forward to seeing your updates when they happen
