I Have Been Told That A Ford Deisel Pick Up With A Chip Will Blow Off A Vette . Ron
77 Vette? Sure. I believe that. They were smogged out dogs. A 77 Vette ran the 1/4 mile in about 16.5 seconds.
2009 Vette? I don't think so. 1/4 mile is 11.3 seconds found

Fastest Nearly stock truck I have ever heard of was this:
Syclone It can run the 1/4 as fast as 13.4 and will beat a Ferrari 348ts
Don't get me wrong. I like diesels just fine and they can be fast too. This one runs a 7.77 1/4.
Banks S-10 Diesel But as you can see it is a bit more than 'just a chip'
The biggest problem with making a truck fast is the aerodynamics. Aerodynamic drag is a logarithmic progression. Traction can be dealt with via 4 wheel drive but if it is still shaped like a brick it is going to need much much more power to go the same speed as the Vette at the top end.
Aerodynamic drag is the primary reason it is very difficult to get past 40mph on our bikes. If someone says they can go faster look for a fairing or some serious hp and gears.
I really like the work you have done on this Tyrslider. I looked up the manual for the greyhound motor and it looks decent. I was looking for ways to improve performance but I didn't see much that was easily doable. Porting and polishing the head may help a bit. You already opened it up with the exhaust and intake so thats done. You may be able to find a longer rod or different piston for more compression but I don't think the head could be shaved much based on the OHV design. You may be able to shave it a hair and get a little more lift on the valves too but if you go too far it will wreak havoc on the valves. The compression ratio is pretty low so you could definitely gain some hp there. A custom ground camshaft would be pretty difficult. Depending on how the ignition is set up you may be able to advance it a bit and use higher octane gas.
