ExcellentPretty sure that's the pump I have on my '88 K1500 5.7L.
Don't forget the modern, high-flow (honecomb, monolithic) catalyst.
Okay I will order one, my original pellet style is in terrible shape.
Asking for cooling system, alternator, and PS problems.
Hopefully not, I will keep a close eye on it though and if I have any of those issues I will swap the stock one back on.
When these heads were rebuilt the 1.85s were upsized to 1.94s which probably won't do any good. Likely will just hinder the flow due to how much shrouding they have now.NOTHING special about a 3-angle valve job.
GM never put 1.94 valves onto a 305. Far as I know, they never got anything bigger than 1.85.
Thank you for your response.
