300 HP from my '67 352 ?

[stephen44]

so i think by using search and google I have actually confused myself more now

as you all know - i have a '67 352 which 2 barrel which i assume is the 208HP version in my f100. I believe this is a stock 352 from 1967 - it even has the tag on the coil bolt ! I have the engine out of the truck now - so am going to de-gunk it - and will be able to get all the casting numbers this weekend.

I read that there were up to 300 HP 352's - from the galaxies(???) with 4 barrel set ups.....

so my question is if I put an edelbrock performer 4 barrel intake on my engine - with a good 4 barrel carb - and headers - will I get to the 300 HP figure or not ? - using the stock heads.

also can I just swap a cam while the engine is out to get a bit more (I want off the line acceleration) and if so what cam should I go for.

this is assuming that the rest of the engine checks out ok.

Thanks for all your patience whilst this Brit tries to get to grips with these engines

I'm not sure about the 352, but the 390's had a high compresion motor in the car, and a low compresion motor for low end tourqe in the trucks. And unless I'm way off help me out guy's there was close to 100hp difference in thier ratings.

[stephen44]

yes - I've been reading some more - and I think I agree with you.

Perhaps some one could clarify.

is speed off the line due to torque or HP ?

[sideoilerfe]

They had Police Intercepter 352s that made 350/HP or so. So I think it is possible. How much do you want to spend?

[stephen44]

well not too much $1000 or so - if i was going to spend much more - i might as well goto 390 + 0.050 etc etc...which at some point i might do - so i was thinking of getting parts that would wok on the 352 right now and then also work when I take it to 390-410.

so may be intake,carb,cam + headers - do you think that will get me close - I am starting to believe i have the low compression truck pistons in - so probably can't do too much !

[sideoilerfe]

Don't waste your money on headers for your low compression truck FE. I had a 352 that ran great and I went to headers and noticed NOTHING. No performance or mileage gains whatsoever.

With manifolds, I like the steel gaskets.

They incorporate a heat shield in the design, which helps keep the heat from the manifolds deflected from the plug wires.

I personally would use them even if the manifolds and heads were brand new!!!

[torquemonger]

HP = speed tourqe is the twisting force put out. the harder it twists the faster it will go, but you need horsepower to keep that speed if that makes any sense.

I have the original 352 with no rebuild in my '67. I put some Flowtech long tube headers, edelbrock aluminum 390 performer intake, and a 600cfm holley carburetor on. It was a pretty good power gain, and a little better fuel mileage. And I imagine with headers, carb, intake, and cam you could make some decent numbers, and stay in your price range.

[SteveC]

my 352 with a cast iron 390 intake stock manifolds and such. I could feel a big difference just going from 2 to four barrel... In granny gear itll about lift the front of the truck off the ground if i get on the gas

So I'm having real problems finding a 390 crank down here - none of the yards keep anything as old as my bump - and no FE engines ....

wonder what the shipping on one would be ?

Probably $40.00-$60.00 depending on how far.

If I had your goal (300 hp 352) with your budget. I would:

Put a set of car pistons in it
Put a stock Ford Car 4V manifold with a Holley on it.
Put headers on it.
Put a decent dual pattern cam in it.

That should pretty much do it for the money and the power and assuming the engine runs good now.

so i have only 50 psi in one cylinder - goes back up with a bit of oil - rest are around 140 - so I think 0.030 over is probably in order !

Can you suggest a "Put a decent dual pattern cam in it." - looking for red light to red light performance only

Yeah, that is a problem, need to get it apart and have a look, you might get lucky and find a stuck ring or bad valve and not have to bore it. My advice on car pistons still stands, but you budget is going to get blown if it needs much (maybe any) machine work. My machine shop bill alone was several times your total budget, of coures I tend to get a little OCD about that kind of stuff.

My suggestion would be a Crane 343941/343942, but since Crane does not appear to be rising from the ashes... going to take some research, Lunati or Crower probably...

[stephen44]

yup - this will be my winter job - now if I can just find a 390 crank

P.S. thanks for the advice - how does one tell if it just a sticky ring etc ?
