a clevo 351 on straight gas, is this a good combo? for power, economical? how much would i have to spend on one to get a reasonable 13 second pass in a XE falcon? what is the best things to do to a 351 on gas?

HIgh Compression is a good start. I have a 351 with Gas research twin carby setup and had it dyno'd about 4 yrs ago with 360hp at wheels. Changed heads to closed chamber, TRW flat tops, rollers, crow stage III gas cam, some crank work and a few other bits and pieces.
Goes like a rocket, burns clean and cheap to run!!

What gear box and diff gears are you running?

I reckon it is achievable, but depends on what else you have in your drivetrain and will cost a few $$$.

What is current engine setup?

By using 302 heads you can bump the compression up to around 11:1.

Use an impco 425 bolted onto a holley 850 base. If you desire or require, you can run two. The Impco 425's are worth about $50 at swapmeets.

The car will have similar fuel costs to a small hyundai.

hmm interesting concept, has anyone done this on a stroker? cause i wanna do a 383 but with fuel costs these days i think im better going with LPG.... how much power can be achieved with a 383 on lpg using extensively ported 2V heads with suitable good springs dampners etc, good cam, and good manifold (weiland or funnelweb) plus extractors etc
im thinking somewhere around 300hp at wheels with butloads of torque? what do you think? im very keen on this idea..

People have done it on 460ci fords, so a stroker shouldn't be a challenge.

If can't afford petrol for a 383 than obviously can't afford a 383.

To save me re-typing everything there's another post in the cleveland forum i've put my opinions in regarding straight LPG clevelands.

Hope it helps,
Greg

P.S. I hope to be running into the 13's on straight LPG and a single impco 425 (ported out to flow more gas) on may 15th. I'll let you all know how I go!

Ive never seem 2 impco 425's on anything other than a tunnel ram.

If your local rego authorities don't have a problem with your manifold and carbies poking out the hood or you can find a twin carby manifold then you can run 2.

Impco make a T bar setup then can run 2 300A mixers, but i've never seen one run and it doesn't look very good.
