then find a 2 bolt 350 block..
add splayed 4 bolt caps, and a 383 set up..
and good heads..
with a little marvals mystery oil and a prime of the oil system, you can get that buddies 350 running.. without opening it up.. spray the mm oil in the spark plug holes and walk away, in a few hours try to slowly by hand turn the engine back and forth... once loose.. spray more in the holes and turn it over a few times.. then prime the oil system.. then fire in the hole..
run that and then start building the 383

I really like burn outs! lol. To be honest my main priority is to get the hp to where i want it, Then start on the rest of the components as time and money allow. I know im doing it backwards haha.

So easy to spend other peoples money..lol
the o/p said budget,, it is a truck it's a c-10 so 2wd mostlikely 4000 lb's ish just like my 71 (mine is a long box, short will be less)
o/p said he wants 400hp at the wheels, let me burst your bubble,
you will have a hard time getting that power to the ground with the factory leaf spring set up as is.. plan on spending bucks here..
400 bones isn't bad for a known running 350 you can get it running now without pulling it apart.. it's not that hard..
it being a 300hp 350 means zero if you are going to rebuild it..
other than check to see if it's standard bore, a 4 bolt block and forged crank..
if it's not as above ,any 150 dollar 350 core will do.. as you'll only be use'n the crank/rods/sheetmetal/head castings(maybe) and the block..
if it's got a forged crank it's worth every pennie of the 400 bones..
rethink this, shooting for the stars is nice.. but an honest 300hp to the wheels will make your truck FLY.. if it hooks..
these trucks are not all that heavy compaired to later trucks..
if use'n a 3spd auto ,use'n a th350 will get a few more to the wheels than the th400..
if going 383, the worth of your bud's 350 is really zero..
as I'd want to start with a standard bore 2 bolt block and add splayed main caps..

How many times do you think you can spray a budget engine with hyper/cast pistons?
If you want a 500 plus HP engine:YOU GOTTA PAY THE PARTS GUY!

|Slammedsi||I guess I haven't mentioned that I'm not opposed to spraying my way to 400whp.|

|vinniekq2||also (forgot to mention) when you are at the rebuilders,look through the buckets of roller followers until you find a decent set.They should be next to free?|

Heres an idea; source a machine shop that sells exchange engines.Ask them to piece a vortec engine together but use a 3.62 stroke crank(stock GM 6 liter) a 4.03 bore. Buy a set of modified vortec heads from a reputable dealer like scoggin dickey. Use a 450-480 lift roller hydraulic cam around 224 ish duration and what ever bolt ons you like.
Drive the truck,,,,,
the engine will make 400 hp plus or minus,will rev freely to 5500 plus RPM,have a nice power delivery and very responsive.
To make more power,expect to spend a lot more money. Quit looking for some super deal in a forgotten barn,just get what works and doesnt cost much. If you dont abuse the engine,I see no reason to buy forged pistons or floating pins etc. DO: balance the engine!

If you still want 400 rwhp and it is going into a (heavy) truck,what you should consider is a bigger engine with more torque.You might need as much as 550 HP to get 400 to the rear wheels. To get 550 hp from a 355 expect to rev the engine to 7,000 rpm (ish) or you need a power adder. Any engine that makes 1.5 hp per cubic inch is a serious engine with all the right parts.
Buying a cheap core is a very small part of the project,,,you will be miles ahead just buying a new block with the appropriate size to start with. A mild 454 is a better place to start if you have little experience with engines.If you rally know your engines then build the engine that best suits your style of driving.

|68NovaSS||Sounds like a good price for a carb to pan motor. Did you run the numbers off the front pad to get your HP numbers?|

SBC Casting number 3932388
I had been on the lookout for a sbc to set on a stand a do a rebuild on and place in my 77 C10. I located a sbc with a block casting number of 3932388. The guy that has it is a good friend. He said he pulled it out of the running car back in the late 80's. Its been on a engine stand sense. Its a complete motor from carb to pan, and never been apart. From my research is a 350 Cubic Inch 300hp motor, from 1969. My friend could not remember what it came out of (old hotrodder that's pushing close to his 80's) but stated it was running when pulled. After setting up so long im sure it needs to be gone through. My question is one, is it worth the 400 bucks he wants for it, and two is this a good motor to shoot for my goal of 400 whp. Thanks for the help.
