If your cam is still stock, that's where you'll find the most hp per $. Something around 220º @ .050 would give a noticeable mid/upper rpm increase without killing too much low rpm power. Next up would be heads (or heads AND a 350 shortblock . The items you mentioned would probably get you a couple horses each with a stock cam.
Sure, get her up to 10 to 1 using worked over and planed to 50 cc chambered 305HO, -601 heads, Fel-pro's #1094 .015" thick shim headgaskets, stock flat-top pistons and install this solid lifter cam from PAW that I figure is this Elgin cam.....
E-1133-P; 280/246, 108/106, .498”, Lash, .030” and .030”
in it from PAW for like less than $50 when I bought mine and have more fun than the Law will allow!
PAW calls it their 264/246 cam so go figure IF they are still selling it and I have one in my bedroom closet for my next junk292/301 engine that I am gathering parts for!
You will be looking at 385 hp at 6500 rpm and 350 t at 5,000 rpm per D2k?
pdq67
PS., you put 64 cc Vortec heads on her and your CR will be about 8 to 1 unless you install stock 1/8" tall, 1/2 round, domed pistons.
I know all about this stuff b/c of my old junk301 from years gone by!
my 67 283 has stock heads (1.94 1.5 valves if i remember correctly), hooker hk32(i think thats the part number) 1 5/8 headers, hei distributor, weiand al intake with edelbrock 600cfm carb with manual secondaries, supposedly has a 485 lift cam already installed, dont know much more about it than that, and electric fan, all sitting in front of a muncie. hopefully i at least have 283 hp at the flywheel. it came with 195 hp stock
edit- pdq what should 283s like these be shifted at? i see your hp quote is at 6500 rpm, but i was figuring on shifting at 6k
Only one or MAYBE two of 283 engines came out w/ the -461x heads w/ 1.94"/1.50" valves and it was in the early '60's so all the others ran heads like the power pack w/ 1.72"/1.50" valves.
Or smaller intake port jobbers than them.
You can run 2.02"/1.60" valve double-hump heads on a 283 IF you use a lift limited cam that's from .450" and shorter! But you'd better run domed pistons and shim headgaskets b/c your CR will be down around 8.2 or so w/ flat-tops!
The 283 I finally got that was my Nephew's had a good set of big valve 291 heads on it, flat-tops and a TRW 308/246, .433" lift hi-cam in it! I figure the reason he got the old junk car w/ it in it was b/c it wouldn't pull me off my Throne, it was so low CR'd!!
Fuelie heads, a 30-30 cam, and an AFB on top, and it should be good to at least 8000rpms.
No, :noway:wait, this isn't 1965 anymore.......................but it worked back then.
Talk about reviving an old thread! Some 305 heads, perhaps?? Wild Bill could help with that decision! If you didn't give up on it and get a 383 or something. --Rich
