reverse cooling systems... possible?
im looking at doing an engine swap. i like the lt1 due to its reverse cooling system but do not like its opti-spark ignition system. and i like the TPI because i am very familiar with that intake system and have alot of extra parts.
question...
can i use the reverse cooling block of an lt1 with the heads and intake of a TPI setup?
or do they have a kit or mod that will reverse the flow of the TPI so that the cylinders are cooled first like with the lt1?

Re: reverse cooling systems... possible?
i was going to build a reverse-flow cooling system for
the 2.8 in my fiero,several advantages to this method
-heads run cooler,so fewer hot spots and less chance
of detonation,while the block runs hotter with much
more even temperature for reduced wear and friction
since the oil film between the pistons and bores is
hotter and therefore thinner,increasing usable H/P
Also,since less heat needs to be dissipated,a smaller
radiator can be used.Back in the mid-,80s ,when the
first experimental reverse flow systems were made,
straight propylene glycol was the coolant used
(regular antifreeze is ethylene glycol) On my fiero
system i was going to have the whole cooling system
in the engine compartment of the fiero,instead of the
pipes going up front to the radiator. was going to
rework a toyota A/C condensor into a radiator,welding
up some tanks,a buick G/N intercooler fan driven off
the engine for airflow,water pump driven off the crank
pulley sprintcar style, etc etc
might actually finish
this one day-have all the parts
I might try a reverse
system on a v-8 third one day,but not my '82 that
car is perfected
