My understanding is that the old Maximum Wedge 413 motor (4.1875" bore size) had the bores notched to accommodate the 2.08 "tulip" intake valves. I purchased a set of maximum wedge cylinder heads along with the factory cross ram intake manifold for $300.00 back in the '70's for a 440 project I was thinking about (would have been 440 in a '65 Barracuda). I gave the heads/intake away to a co-worker for free about 20 years ago when I eliminated my storage space.
Using little tricks I see.
Not sure either, @66fs would be the fella to answer that.
***** already in over 20 + books from the 60's,70's,80's. Why present it as "tricks" at this point.
Because new people are getting into it.
You mean the 2.18
Just because I have videos of my own doesn't mean I'm trying to compare.
I believe its because they're not seen as significant being that their only use is in very uncommon situations rarely encountered.
Actually, the bore notches on the factory MW engines were done on the exhaust side…….to clear the 1.88” exhaust valves.
I’m not putting you against anyone or anything.
Possibly true, no doubt
surely no, because unlike (for example) a small block ford the valves aren't in/ex/in/ex/in/ex/in/ex so only 2 cylinders would see any benefit. the other 2 would be worse.
No, I'm pretty sure they were 2.08". But as mentioned above, the 1.88" exhaust valve is probably the reason for the cylinder bore notches.
Pretty sure the dowels would to offset up or down not forwards or backwards. Hopefully 66fs chimes in.
I always forget about the early Big Blocks having the small 1.60 exhaust valve . 1.74 stock
Any way you want to clock them. As long as you're rocker oiling feed still lines up LOL
I used offset dowels to center 1.88 "J" intake valves on the 3.665 diameter bores on my 273. I was worried, needlessly, that they would hit the block. I got the offset dowels from Ed Hamburger. I think I only used .020 or .030 offset dowels and some were 000 offset. You should assemble the heads to the block and take measurements. It does not make sense to use offset dowels to try and gain flow since the valves are EIIEEIIE. See post #87
Well people mention it to Unity Motorsports Garage hopefully he test it out, but either way the notch got most the flow back and if you can gain a little more by offsetting bonus if not oh well.
That's what they did and got most of the flow back which to me is good enough.
Their also thinking of boring on a offset, which almost got all flow back but I think is over doing it in 99.9% of all cases.
Not true, off set one way for the proper cylinders and then the other way for the other two.
I'm not much into videos, but since Salters 383 build was posted I've been checking out his channel, very informative in every aspect of engine building and making power.
I meant with dowels...
