So I'm planning on going to the track Saturday, it is 80 miles away
I have a goal, 20 mpg and 12's (20.0001 and 12.999 would be fine by me)
that is my goal, now here is what I have:
the car in my avatar.
motor is a salvage 99 suburban 350 vortec.
I ported the heads (no bench), lapped the valves by hand
got a regrind 230* - 480" hyd roller
Q-jet carb with edelbrock high flow needle and seat
air-gap intake with carb adapter
factory exhaust manifolds
HEI locked out at 36* or so
(if not mentioned it's all gm right down to the gaskets)
transmission is a 700r4 with v6 s10 converter stalls 2300
gears are stock, which I was told were 3.07 when I bought the car but afterwards I read that only manuals had 3.07's mine is a 2.79 dana 36 auto car...
rear tires are toyo proxis 275 45 16's (smaller than the cooper cobra 255-50-16's, why?)
so that is my goal and what I have... (aftermarket parts: regrind cam, airgap intake, carb adapter, needle+seat, tires)
will I get my 20 MPG goal? what do you predict my mileage at?
will I run my 12's? what is your et prediction?
will I break the dana 36 (or something else?)
