I have a 1978 Chevy 454 truck motor. It has 8.25 compression it it all stock but runs very strong. This is in a 69 el Camino with a th400 and 2.73 standard cog 10 bolt. This is a street car only and I am very happy with the power it gives.
I recently changed cams to the Melling 22216 marine cam with new GM lifters with the split base.
I am thrilled with the additional performance of this cam, along with its cool, low key, lope at idle..
My brother gave me three Quadrajets, he is cleaning out one of his storage spots. God only knows what he has stashed away. One of the carbs has a straight in fuel filter and the other two have 90 degree inlets. He says one style is for Pontiacs and hard to get..
I have three hangers and four sets of rods.
2- L hangers.
1- J hanger.
2 sets of CK rods #7045779 S-tip.
1 set of DP rods #0686 S tip.
What would be the best hanger and set of rods to use. Or do I have to do experiment..
The carb I have on the engine is stock and came with the engine.
My car likes the air and fuel mixture set at 3 and 3/4s turns for the best idle to off idle performance. This makes a very big difference in off idle performance. Its real strong off idle all the way to 5500...
Cliff, thank you so much for the cam recommendation!!!
