One of these days I plan on either 1) porting and polishing my stock heads or 2) buying a new set of heads. These are for a 68 390 FE. which of these is will be the better option. ive heard that 390 heads can be ported to 300cc of intake which sounds ridiculous..is that true?
i do not have the numbers right now (im 160 miles away from my truck right now at school) and i intend on making it just a hot rod, something to drive around the block and shakle the woods up a little. and i haven't layed out a full plan of what i intend to do yet.
No sir, its a truck motor. Came on the f100. i just had it rebuilt about 4 months ago, bored .030 over and i had a 270 cam stuck in there. ive put 1600 miles on it so far. i plan on puttin the 445 stroker kit in it when i have the money so i figured some heads would be nice too..i would really like to keep the stock ones on there to maintain the original value. i just figured i would open them up some, but i didnt know if buying new heads (maybe the edelbrock 185cc heads) would be a cheaper and easier investment
new heads are going to be far and above 50+ year old technology, even ported. A good porter can get you some additional power out of your existing heads, but by the time you've paid him his worth, you're probably going to be about 2/3 the way to the cost of a new set of much better heads.
BTW a 445 stroker is going to want a lot more head than a 390. Just one more thing to consider.
So would you say it would be worth putting about 1500 in a set of Edelbrock heads then? that's what i'm looking at...unless there are some better and for a lower price
Modern heads, cam grind, carb and headers are the way to go if you want a hot rod. These engines suffer from low compression and poor(at best) exhaust flow from the heads and exhaust manifolds.
Your planned stroker kit will need some airflow to support the increased displacement. The edelbrock heads are your answer. FE's "wake up" really well and gain 70 hp easily with better flow even on a stock short block.
With the displacement you are thinking about with the edelbrock stuff you will have 400 hp and close to 500 ft. lbs. conservatively.
