You're no fun!

Sorry man. I just don't want folks to make my $10,000 mistake overbuilding.

We talk explorer swap, we need to talk ford van 351 swap, i bet those are cheap. Minus top end. 96 van in phx craigs 5.8 $3000

Doesn't the 96 5.8 need a lightning manifold to fit?

Yup...or the adaptor BC sells or the marine cast iron version of the lighting intake.

Or cut a ginormous hole in the hood to clear the truck intake. But if you're going to do that you really should be looking for a 3881 intake assembly.

What would be good would be a low(er) profile upper for the 3881's 3884 lower, which is available separately.

Any thoughts on the Flo-Tek 203-505 (1.94/1.54, 58cc) heads? smaller chambers to bump CR a bit, smaller valves to eliminate piston/valve clearance issues, under $1K for a pair.

The 302 race engines I built for our team had iron heads with 1.94/1.60 valves and 0.610" lift solid-lifter cam. I had to flycut additional clearance in to the top of Diamond race pistons. FWIW.....I always clay the pistons to check.

I didn't think they produced the adaptor any longer?

Time for a slight hijack. Do any of the aluminum heads have the plug angle for long tube headers? 351w

I'd call specific head and header tech folks.

The FloTek is probably most suited for your requirements. The GT40X is the closest to the iron GT40, but still higher cost and less power compared to the FloTek. The Ford heads are great, but bang for the buck, FloTek is probably the only sub $1K aluminum head option for stock piston.
