HELP: Cylinder Head and Cam Suggestions for 318

Shane65 said
What's up guys? Hey so wanted to reach out to the experts here... I'm really wanting to wake up my 318 a bit. I've been researching a lot but wanted to reach out and see what you guys think. I'm debating on buying new heads and a cam to make some power, but I do have a set of old 587's that could be rebuilt. Wondering if I should pair those with a 340 cam or see if there was a better route to take? I'm hesitant to go magnum heads. Read a lot of good about TrickFlow heads but looks like they don't stock them anymore... Would eventually like to get this motor somewhere around 350 hp for a fun street car, just looking for the easiest most direct way to get there.

It's a pretty stock 318 in my 68 barracuda. Currently has a 1406 4 barrel Edelbrock Carb, Weiand Stealth intake manifold, and Dougs D453 headers... Stock gears, 255-60-15's out back

I'm fairly mechanically inclined, but I've never taken my engine apart. I would like to do this job on my own if possible, while keeping the bottom end stock for now. What you guys think?

Here Is the magic to your answer:

1968 9.2:1 cr 230 hp 318, just for starters. Stock in 1968.

If your valves have not pounded into the 645 open chamber heads with the non hardened seats, then would say the 340 cam will round it out nice.

If the heads are compromised, then upgrade to the 302 closed chamber heads and pick up another 1/2 of a point of compression ratio, and can also go with the thin Mr. Gasket 1121G .028 ths thin head gaskets for even more on the compression ratio bump.

Getting in the area of 9.5:1 cr now. Next add a LD4B 318 aluminum intake manifold and a 1406 Edelbrock carb.

300 + hp here we go.

Don't forget the 2 1/2" full exhaust all the way out the back.

1968 9.2:1 cr factory stock pistons with the light free floating rods.

782 light weight free floating rods on the left. Heavy 645 rod on the right above.

You asked for it: Here You Go!
