those 64 v8 manifolds really choke it down, ports are tiny, that drivers side with its 90* bend sucks...,.. guess it all depends on the build..
What I just love is, when people have those manifolds for sale and mark them as "HP manifolds" like they are some kinda holy grail. All those early ones are the same. LOL
Do the 340 manifolds fit the early A bodies? I didn't think they did. I have a set of 64 manifolds right now.To the OP, why not run the 340 manifolds? Either style, early or late will fit without power steering.
Yes I know I'm at a dealing with small ports. But not looking to set the world on fire. Just build a decent street motor. I'm a believer in not every street car needs 600 HP.those 64 v8 manifolds really choke it down, ports are tiny, that drivers side with its 90* bend sucks...,.. guess it all depends on the build..
The loss of horsepower is mostly at high rpm- for a mild build on street driver- may even help with low end torqueHow much horsepower could I make with a 318 4BBL using the 1964 exhaust manifolds? I know the driver's side is pretty restrictive. I would use a roller hyd cam and pump gas friendly.
Pretty much all the information except for the 318 and the four barrel?thats all fine and dandy, and yes i understand that not all street cars need 600 hp. but your question is missing a ton of information.. so its a roller cammed 318 with a 4bbl.. is it all stock in which case the manifolods should be fine for daily type of street use. or is this a built motor? 400-500 hp??? if thats the case they will choke the hell out of it..

I'm bench building a motor right now. Just trying to get ideas and pick people's brains that are smarter than me. Trying to advoid headers on an early A body. So any info is good info.thats all fine and dandy, and yes i understand that not all street cars need 600 hp. but your question is missing a ton of information.. so its a roller cammed 318 with a 4bbl.. is it all stock in which case the manifolods should be fine for daily type of street use. or is this a built motor? 400-500 hp??? if thats the case they will choke the hell out of it..
I might have to look into this further. Thanks.With no power steering, yes. They are TIGHT. Tight enough that they may fit on one and another may have to shift the engine one way or the other, but they do fit.

Thanks RRR. I'll search tonight when I get home.Do a search....and keep searching. LOL There are people here who have done it and posted. The search function sucks hind tit, but if you keep playing with the wording, you will find it.
I used "340 manifolds" title only and came up with 7 pages of threads. Many are sale threads. I would scroll past those but lots of good information there. Search Results for Query: 340 manifolds | For A Bodies Only Mopar ForumThanks RRR. I'll search tonight when I get home.
I'm planning on no P/S or power brakes. Haven't decided on transmission yet. I keep going back and forth on 4 speed/ 3 speed auto. 8 3/4 with 3:55 and either a 27" or 28" tall tire.I wouldn’t worry about how much power can be made but focus on everything else afterwards. On the engine build, I would yield at 9.0-1. A tad more is possible but the octane required may start to fall short if the cam isn’t big enough duration wise. This is an exercise of caution. Then select the cam. While the manufacturers list an rpm they operate in, it is a general one with the bigger engines in mind. So select the one down from the most performance oriented grind that works with your converter and gear ratio.
On the exhaust, duals with an H or X pipe will top it off just perfectly 2-1/2 max size pipe. And that is plenty large!
Which model is your transmission, rear end size, gear ratio and tire size?
IF this were I, I would use the 4spd trans. A 245/60/15 wheel & tire. (27 inch max tire diameter!) I'd skip the Hyd. roller cam myself. Umless you have a Magnum engine.I keep going back and forth on 4 speed/ 3 speed auto. 8 3/4 with 3:55 and either a 27" or 28" tall tire.
Yes I'm leaning towards the 4 speed. 255/60R15. I figured the roller cam can provide better cam profiles.IF this were I, I would use the 4spd trans. A 245/60/15 wheel & tire. (27 inch max tire diameter!) I'd skip the Hyd. roller cam myself. Umless you have a Magnum engine.
A cam duration @ .050 of 224 (-ish), 1.6 rockers, valve springs to match. (Call me crazy, but to expand the camshafts flexibility...) Top of the line Rhodes lifters, (Also available for the Chrysler Hyd. roller cam) adjustable duration units set at the max on the intake. Stock lifter on the exhaust.
OE or Edelbrock Performer intake. 650 cfm carb.
