I'm embarking on a sl6 to 318 swap. (automatic 904)
My wife says this car MUST be quiet -no headers. It must idle nice. It must have AC. It must not overheat. It must be fine with 70 mph. That said, I can spend some cash on this build no problem but don't want a fiddly exotic tuning nightmare. I think I'll shoot for 250 HP and as much torque as possible to get it off the line with my 276 gearset.
I'm gong to rebuild the 318. plan on bumping the compression up with pistons
Heads? 360 heads and intake- stock
5-650 vac secondary carb to retain a bit of mileage.
slant torque converter might be a good idea?
Bast option on exhaust? like a high flow cast iron manifold.
what cam to use? power just off idle-retain torque- sounds like an 80's truck cam but cam choices are infinite and I'm not "in the know" about them.
what kind of head mods would be most effective? I thought just a bowl polish and knock back the heart tip? Full porting would just slow the charge and cost torque?
Going to an aluminum radiator with dual electric fans-Griffin makes the best ones I've seen around.
Of course I have electronic ignition and such. I just need to talk to my engine guy soon and bat around ideas
