Hi guys. i am a newb to this forum. And to working on this kind of engine. So first let me explain my truck. I have a 1990 C1500 350 5.7L regualr cab short bed. This was my grandfathers truck that passed away when i was 9. I inherited the truck after my grandmother died afew years back. I have searched on this forum for lots of things and am sort of getting no where fast so im just gonna ask the important questions i know i need help with. ok So i need new plugs and wires air filter oil filter ( not sure what kind to get to get the most power and performance for my truck) and also i need two new mirrors (review and driver side) and a new windshield if u could point me in the direction to find a good deal that would help me alot. And finaly i wanna replce the solid back windsheild for one that can slide open. THanks

 

Welcome and good luck. Try http://car-part.com/ for used mirrors and glass if you're looking for stock replacements.

 

Glad to have you!! As far as a tune up, these are just my suggestions from experience I have had with them. Plugs- NGK, Wires-MSD 8.8mm with MSD 6A Box(optional), Oil- Royal Purple, Air filter- K&N or Tru Flow if they make it for your truck. As far as other mods like exhaust and intake, not sure cuz I think you have a TBI set up on that truck. Find out and let us know.

 

I had the same truck. 1990 Chevy Silverado, 5.7 350 with auto mantic tranny 700R4.
Okay here are my suggestions as far as a tune up goes. Stock Gm wires, cap and rotor, Bosch Platinum plugs (regular Bosch). Oil and filter your preferance. Tranny filter and fresh tranny fluid.
Performance mods that I had... Edelbrock intake, JBA shorty headers, ASP underdrive pulleys, K&N airfilter with homemade built ram air kit, stock y-pipe into stock cat into a glasspack dualed out. Hypertech thermomaster chip with 160 degree T-stat. And I ran regular unleadede to keep the gas mileage. It nevder clattered and when I ran premium fuel it screamed like a scalded dog but drank the fuel like a crack head feeming for a fix.

 

Thanks everyone u all have helped alot. ill keep you all posted as i work on the truck

 

Looks like pretty good advise so I'll keep my 2 cents in my pocket for later. Welcome aboard and good luck with her, that's a nice truck. I had a '91 that I ordered, 1500, 5.7 lt, 700R4, 3.73, extended cab, short bed. Oh yeah Black.
