does the first table for the low manifolds say 471 hp for the ZZ4 and the later table for all manifolds say 451 hp? maybe I can't follow the article

linkage needs to be gone over carefully, maybe disconnect the linkage from each carb leaving a functional return spring for each, I don't know anything about the choke and fast idle setup for that type carb but tinker with them one carb at a time, obviously check the base gaskets for vacuum keaks

is there a cheap from Amazon style tool that will measure vibration?

Masterflow 885 grout is commonly used in drag racing with stock type iron engine blocks

on the Motortrend cable channel the other night they were driving a used up SBC that was going about 10 miles per quart of oil, what current oil and or additive will help with terrible ring seal for let's say a month?

how do the exhaust manifolds from a C60 type 427 truck compare to pickup manifolds? manifolds are going to hurt power in the mid range compared to long tube headers

most replacement pistons have reduced compression height to account for decked heads and block, if those are stock bore you might use a straight edge ruler and feeler gauge to find out what you have

I wanted to order studs, plates, and rockers over the holiday, these no name chinese heads take about .670" thread depth before intruding into the port enough to make me consider cutting some off

does anyone know the thickness of their SBC adjustable plate? .090" ? more ?

people are reluctant to use the oem filter adapter because it looks cheesy, they feel for the money invested in their engine, it deserves a billet piece, do boats have room for the truck size filter? are there any of those independent tests that have measured the flow for the big filter?

the whole point of using the crank with bigger counter weights is to avoid external balancing, using the reduced compression height pistons pretty much ensure low piston weight, unless you are going to use power adder pistons with an iron crank

what makes a tool steel lifter superior to some other alloy? for instance the 4140 that spring retainers are made of? do they have the same crown as iron lifters?

what does leaving at a higher RPM do to your 60' time?

there is no "heavy spring" in that style carb, it must be from something else

what does that divider in the water outlet accomplish?
