Default Parts help please

Gonna be doing the cam upgrade soon and wanted some help on part #'s and or recommendations.

Local shop is gonna do the head word (port polish) same treatment to the intake.

I just wanted some suggestions as to what pushrods to run, lifters, springs and injectors (if needed). Im also wanting to upgrade the timing chain as well. Currently has 84k miles.
Currently on 52mm TB, not sure if I should upgrade that as well. Has all the bolt ons, long tubes, no cats, underdrive pulley.

The motor has been redone about 1500 miles ago. .040 over pistons, has the mild 304 cam everything else is the original items.

Anyother upgrade suggestions is appreciated.

save up a few more $$ and get a H/C package from AI you wont be sorry

regardless of what you do don't expect to just toss parts on the motor and go super quick it takes work........but with some work ive yet to have anything they have done for me not exceed my expectations

Yes, also Elliot was on my list. But i might go with my local shop. Their port guy has done a lot of good work and good reviews from locals.

At the moment just looking for supporting upgrade parts for the swap to try to same some $. Im sure shops charge a bit more for those parts.

the 52mm throttle body will be more then enough for your build, my head and cam package im currently running a stock cloyes replacement timing chain, haven't had issues yet but my car doesn't go to the track and i don't drive it often. Get some 1.6rr and some slightly stiffer springs to suport the cam you have. I've read stock springs can barley support the stock cam in lt1s anyways .
