From the dyno plots I had seen recently of a bunch of cams being tested with I believe a victor jr intake, the carb made more HP on every cam than the FI did.

I can't believe I'm going to say this, but screw all that LS crap, go grab a dime-a-dozen 350 block, toss in the crank from the 283 (especially if it's steel) with some 327 rods, flat-tops, balance to the moon with either worked over factory heads or some affordable Dart iron heads, cover your roller rockers with valve cover spacers and those nicely patina'd 283 covers, paint an aluminum intake all scroggy to match, stick the stock air cleaner over a modern 4bbl and get it awn. Small-journal 302, old school style for an old school truck.

I love those trucks lowered, but don't be afraid to hoist the front end up gasser style, throw'n sparks off the back bumper is way cooler when the front end is in the air.

Good luck with whatever you build it like Skooter. Yours will probably be done before mine because I'm slow. Maybe this will give me some motivation to finish mine.

Drop spindles in the front, notched frame in the back.

Sounds like a great project. I can't wait to see some progress pictures.

You're preaching to the choir.
If I can't go totally modern, I'm not going to dumb-down a F.I. motor to use a carb. I have access to a small-journal 327 block to stuff my 283 crank and rods into to wind up with the same effect, however, I'd like torque below 4000 rpm too - that's why I'm considering a 377. A few more cubes and similar piston speeds to wring out 6500 rpm (or more )

I will use all the old patina-ed parts I can, with the exception of buying THESE.
I will also look for an old offy or weiand aluminum manifold with the hole for the oil-filler tube to finish it off. I am also working on figuring out a good way to hide programmable spark timing.

Your wife basically said it reminds her of her fathers car... which probably had some crappy 4 cylinder in it.

Thus 22R.

OH SICK BURN!

All kidding aside, I'd love to have some old iron with a modern jap turbo 4 banger. Oh how it would anger people at car shows *lol*

I've got a vintage cross-ram dual quad intake...but it's not for sale, and I know a guy with a triple v-belt driven 4-71 blower topped with (4) 1bbls....he says he won't sell that either....

Petronics conversion in a vintage Mallory or Accel points distributor body....ooh yeah.

You're no help, Jackass!

I'll find something on the H.A.M.B., I'm sure.

Looks like I will be picking up a 383 stroker motor this weekend.

A coworker has a vintage aluminum intake - but it's single plane, so not sure I'll go with that.

Easyest way to do up grade is to swap out entire frame from early to mid 80's truck. Easy swap by far possibly swap frame mounts if need be other wise frames are prity close. Or I have seen people mate a 70's camaro front sub into frame and use a 12 bolt car rear end.

Ya it is hard to beat the HP from a carberated motor. But depending on what he is using it for it is eaven harder to beat the dependability of fuel injection. That and no offence but some women don't under stand the full concept of how to start a carberated motor. Due to they ae to used to fuel injected ones.

How is this bad? Then the woman will never take his truck.

Frame will stay 1966.
Front suspension will be sourced from a 73-87 1/2 Chevy.
Rear end will be a 12-bolt similarly sourced and I'll make my own panhard setup for it.

And as far as my wife, she is smarter and better versed in internal combustion engines than 95% of this forum.
She already understands the drawbacks to a carburetor, and that is the reason she wants to keep one.
