take it its in a VH?
best mod will be a thermo fan cause you can keep it for when you get a 308,
other than that
extractors
heads
cam
or for alot less than the above, get a 253, then everything you do to the 253 can also go onto the 308.
at the moment im half way thru making the zorst manifold for a turbo conversion on a blue 202 in my VH.. i will post pics and ETC up to help out with ideas soon ( i ned the car done in 2 weeks SO you shouldnt be waiting too long)

Some original photos have not been recovered yet.
my mate had a VC, same 202 blue motor. His had a lightened flywheel, extractors and decent exhaust, 350 holley, sports air cleaner. was also a 4 speed manual, and this thing *** flew...for what it was any way, could give some 308;s a head ache
our race engine (Speedway) has been stroked, forged pistons, yella terra head, roller rockers, 500holley, extractors, 2.5inch mandrel bent exhaust, lightened flywheel, ummmm a **** load of other things.. now we just gotta replace a big end and chuck it in the car
