One thing leads to another... mean 318?

Lots of work for a teen. have you looked into a Jasper or board sponsored reman 360? Cam it and go. IDK if a stroker 318 will run like a 'scalded dog' but it will pull like a pit bull. gotta watch your piston speed.....400 HP 360 Mags with carbs are not uncommon with just cams , intakes and headers. sounds like you already got those! (Maybe not the mag carb intake......)

Check these oit. The first linked book has easy calculations for piston speed like kim mentioned.
