so my boss and i talked a lot about what i want to do with this 318. he looked up parts....ran some numbers......wont be easy to get the 10:1 compression ratio i want unfortunately. soooooo.......he talked to a friend of his who has a 4000$ 450HP LA318 engine. my boss's friend told me to rebuild it stock.
we mic'd the block, cylinder walls have almost 0 taper to them. so they are in really great shape. we discussed it more and came to the conclusion that we will cam it, install bigger valves, port the heads, gasket match, and thats it. basically all top end work. we wont bore it because its not needed and boring it out to the .030 pistons i do have, really wont add all that much compression anyway.
we ran the numbers on a program he has. with the stock valves (not the bigger size like i am wanting) it came out to be almost 300 HP @5000 rpm with almost 400 ft. lbs of torque @1500 rpm. pure torque right out of the gate. which is what i am aiming for.
we also discussed intake and decided that the edelbrock performer is the way to go. unfortunately, i sold mine thinking i was going to go with the rpm air gap. my boss is a stubborn dude and wouldnt listen to me when i said the air gap does work with 318 heads. "because edelbrock says its for a 360/340 engine". but in his defense, the cam he wants to use matches the performer intake better than it matches the rpm air gap intake. so there is that.
gotta figure out if i need oversized crank bearings before i buy a master rebuild kit. bringing the crank down to the shop to see if it needs to be turned....then its just buying parts after that.
thinking we are going to throw a 600cfm holley on it. sorry for the book fellas, just excited that my truck might be on the road here soon. excited
