Here's a good question

Thank you for the info. That sounds interesting. It has possibilites. Anyone else? Any other ideas? I like to be different as this will be a business promotional vehicle. Tires are 10 x31 x15 not real big.

I also have some new parts but not sure which way to go.

Dual quad low riser with dual edelbrock carbs set up as progressive? (cool factor)
Dual quad low riser with dual quadrajet carbs set up as progressive? ( not possible I found out)
Torker 2 and a quadrajet or edelbrock carb? (found out torker has no bottom end torque)
What about a rochester 2 bbl and a quadrajet set up on a progessive setup?
What about a rochester 2 bbl on Torker2 intake?

I have all the parts. I want gas milage but it would be nice to have some power in reserve for passing power.

Rayfin,

You may get better economy with a 305. 25 years ago GM went to that engine for emissions and economy-the school of thought, at least back then, was a longer stroke and smaller bore produced better economy. I don't know what the school of thought is today in regards to economy.

A quadrajet or spreadbore carb utilizing small primaries will probably be a more economical carb than would a 2 barrell. The 2 barrell will probably have bigger jets than will the primary side of a spreadbore carb set up for everyday driving/economy.

Also the bigger the tires the more economy will suffer.

Hope some of this helps!

I appreciate that. Like I said I never worried about mileage before. I was wondering what mods I should do if any. I wonder if a beefed up 305 would get better mileage than a stock 350. I decided on a performer intake and either a quadrajet or edelbrock 600. I have both. I suppose small tube headers would help a lot. Compression would help. I wonder about valve and port size also...I guess I'll experiment. THANKS for the advice. I know this isn't the best place to ask but you guys know your stuff.

Found an aluminum water pump today for $40. This should be a fun project.

Hey Rayfin,another thing,if you use an EGR valve,with the proper thermal vacuum switch (usually in the waterneck,usually broken/disconnected on most 'beaters),it will save you a little gas.The truck will run partially on unburnt exhaust gas during coast/decelleration.An Edelbrock Performer w/EGR would be good,or an old Edelbrock SP/2P (I mean OLD) w/EGR would be even better.If I think of anything else I'll post it.-Lew.

"usually in the waterneck,usually broken/disconnected on most 'beaters"

I wondered what all that bull**** on the water neck was...cool.
