Ram Jet question.
Can the Ram Jet intake be purchased separately? And, would it be possible to run the ram jet w/ a 90-93 SD computer and harness?

Thanks for the parts list, right now we are trying to validate cost effectiveness of the set up. Anyway I go I need a custom chip. This is for a 58' Chevy truck w/ a vortec headed 350. It has a Comp Cams XE264 HR cam, .487/.495 lift. The suggested powerband is 1200-5200. It seems like that cam would mate up to the characteristics of a Ram Jet nicely. I just need to determine if a GM SD computer w/ a good PROM burner will make this thing work right.
The other option we are exploring is a SDPC vortec base, w/ an Accel Super Ram plemun and runners.
If anyone has any suggestion, opinions, tips, or otherwise.....feel free to express your thoughts. I would be very interseted to hear them. Thank you to everyone who responded.

the ramjet is a more suited manifold candidate
than say a miniram. the super ram is better
in relation to torque than high rpm. trucks
generally run in the 5500-6500# class. to make
them run like an f-body car is tougher. unless
you are going to run strip racing, gear your
decisions on the low end torque factor. the
drivability is better, easier to tune, and less
wrench time.
unless your engine is going to 6000+rpm the
stock TPI style would be best. larger tubes
and the vortec base.
chip tuning is a bit tedious but is doable!
vortecs have been running 15-22% more in fuel
table adjustments. timing because of the high
lead or vortec has to be trial and error.
the gm 7730 SD computer is probably the easiest
to tweak.
TIP: use the felpro 1255 intake gasket during
installation. the gm composite seem to leak with
time. vacuum leak is what a couple of customers
have experienced.

The truck in question only weighs about 3400-3500 lbs. So, therefore weight is not a major issue. This truck is not a race - orientated vehicle. It is geared pretty well though, 3.73's. It has a 700R4 w/ an SLP converter. I know nothing about PROM tuning - so that will be farmed out.
