Restore it, Dont part it!
For pump gas what compression is desired? And with stock 318 would a bump in compression help without adding more flow? Just curious
Thank you the cam is new in the box i bought it a while back and an just getting around to starting my project. I want a cam that would be streetable good on gas reliable and something that i wouldn't have to start changing other parts like upping my compression and valves and heads etc that why i went with a mild cam from what i read a stock 318 with a 340 hp cam really wakes up with headers and a four barrel this is the closest i could find to a stock cam without changing everything i plan on running stock spring for now i will change them later on i want to run a weaker spring untill the cam is broke in im not worried about floating valves cause im not gonna run rhe crap out of it lol it will be lucky if it ever sees 3500 from what iv read they this cam is ok with stock springs up too 5 grand i will never ever turn mine that high I am considering going ahead and rebuilding the bottom end and getting new pistons to boost my compression some thanks for all the avice keep em comingHappy fathers Day dartfreak
I'd rather use a regrind than that 50 year old 204-214 design, or a stock cam
At least you do not see Edelbrocks price for it
check other mfg like Elgin, Wolverine, Speed Pro
WE just specked a 254-262 Lunati Voodoo but is it worth the extra bucks? You might get lucky with Racer Brown but
Comp, Crane, Erson, Isky have nothing any better
good news is that quality is good, resonably foolproof installation just use moly paste (not liquid) and some break in oil (not DIY additive) and prime oil system with a hex shaft and drill
I see where this is discussed on page 2
Lol i didnt mill mine when i put stock 360 heads on a stock 318 it was weak as pond water i couldnt pull a hill lol maybe shaving them down .40 would help idk how much does a machine shop charged to mill 40 tho off i could always try both i already have the heads wouldnt be that hard to swap them back outI've never put 360 heads on a 318 and lost performance. I'll take flow over compression any day. I usually cut the 360 heads about .040 and bolt them on.... (and NO, I've never cut the intake!... LOL).
If all a person is concerned about is "off idle snap", then stick to the 318 2bbl cam and 318 heads. But when you can't pass a stock 2001 Buick LeSabre 3.8 at 55 mph, then we can all start another thread
Thank youIf you still need the spec for the Melling spring, it is
VS-1120 : 1.9400 free length 1.4940 outside dimension 1.0800 inside dimension .207 wire size 91-101 @1.65 closed position pressure and length (aka- installed height) 231-245 @1.22 open position pressure and length, 5.625 RH number of coils, 1.1000 solid height.
Just so you know, factory 318 4bbls cam with 360 heads.....Lol i didnt mill mine when i put stock 360 heads on a stock 318 it was weak as pond water i couldnt pull a hill lol maybe shaving them down .40 would help idk how much does a machine shop charged to mill 40 tho off i could always try both i already have the heads wouldnt be that hard to swap them back out
Carry on, my good fellowIm not one to argue but I dont think that's right. Im not 100 sure but that dont sound right
Like I said i may be wrong all the casting numbers for 318 heads all years all combinations are different from 360s all 318 heads have 178 valve all 360s had 188 340hps had 202
That is very interesing where these sold in new cars or was it an aftermarket dealer upgrade type thing? I have never heard or seen that before sorry for being skeptical its nothing personal I am a little hesitate to believe everything i read in the internet with out facts or proof if you know what I mean! Lol thanks for that info thoI've drove 'em, and I know people that race these in stock eliminator, but here is a piece of an article.
1978, MOPAR first sold the 'LA' version of the 318-4Bbl. They simply bolted on a 360 intake/thermo-quad. Shortly after, a (so-called) H.P. version was 'unleashed' on the motoring public. This version used the (current) 360 heads with the 1.88/1.60 valves. In fact, this H.P. 318 was available through 1984.
Iron heads and you are not a super tuner 9:1 compression will help without more flow but just multi angle valve job and blending the new deeper valve job into the casting really helps- with less than 1/2 inch cam lift putting in what starts off as a 2.02 valve cut down and with 30 degree seats helps (you cut down as going 30 degrees makes it too thin on the edge, and back cutFor pump gas what compression is desired?

Sold new. Beginning of '78 they just bolted the TQ intake/carb on top of the 318 heads. Then they put the 360 heads on with the combo. You can go to any 318 4bbl, common in ramchargers and maxi vans, especially from '81 -84 and it will have 360 heads on it. Cop car diplomats with the 318 4bbl will have 360 heads as well. I've owned them, and know others that have owned them as well. these performed very well right out of the box, but were choked as well with single exhaust, and cats.That is very interesing where these sold in new cars or was it an aftermarket dealer upgrade type thing?

318 heads work well on 318's, especially with a little home porting. 360 heads work better IF cut .040. You can use the 318 push rods/rockers. they are the same as 360's anyways.Was that an allpar article? I found it and read it that is some good info thanks!! So it said evey .005 milled off the head is 1cc so i could mill .50 and take of 10cc with a 73cc head that would put me back to where i am now with stock 318 heads could i run that setup with factory rockers or would i have to switch to adjustable like it says in the article? Cause lets face it thats more $$$$ lol does anyone know how much the average head milling costs?
