yes its VERY easy to upgrade the distributor, one of the very first mods I did to my car was replacing the darn HEI, the low rpm multi spark helps the idle, the new distrib and ignition and wires pulls easily to 7K rpm
with this..

the MSD 6AL ignition
is just fine for most street/strip application when matched with the correct components

(appears to be a similar distributor, but IM sure you still need the adapter listed lower in the thread)

theres a dozen ways you can go with headers and ignition wire, but Ive used these on several cars with good results and its what my race vette runs

if your replacing a TPI intake with a tunnel ram, HOLLEY STEALTH RAM or other intake requiring a small base diam. distributor, a gen 1 sbc distributor that fits physically, into the intake can be used in most cases, it can be made to function, most guys use aftermarket remote coil distributors, but the small diam. camaro distributor works,I used a HOLLEY 890-160 distributor

*these adapters are very easy to make from salvage yard parts(wire plug connectors)

find the break in the wire and solder it with quality flux and tin/lead solder,to a solid electrical connection then use shrink tube to cover the splice

or it will eventually over heat and start causing no start, or irregular intermittent no start issues

youll find you can replace the whole distributor from several sources,
at times , cheaper than you can buy all the component parts
but shop carefully as quality varies
