For the guys with the built engines and lower compression, how much worse has your fuel economy gotten
Built engine economy

If you're worried about a slight loss in fuel economy, don't build your engine.
There should be less than 3% change in fuel economy depending on your driving style and tune.

Where did you buy just the boss short block?
You can buy it from Ford Racing. Call up Tousley Ford for a great price on it. I purchased all the parts separate and assembled it myself. Saved me about $1000. Think it cost me about $2400 including a new $1200 block.
Economy and power dont go hand in hand
Wow! The boss parts are all pre balanced correct? That why you could just put it together?
Good to know. Did you use boss oem bearings as well? I saw that you made big power on your setup so it's seems the boss bottom end is pretty strong.
How much can these things take? This may be an option if they can hold up to alot of power. Been looking at the mmr setup.
Yes I used the Boss bearings also. As for how much power they can hold... nobody has found the limit as far as I know. There's guys making over 800 without problems. Ford claims the rods are the strongest rod they've ever made so I'd say the weak link are the rod bolts.
Tousley has the blocks for around 1200?
Oh ok thanks.
I'm already being built but I was wondering if it'd be a huge change. Bc our tanks aren't very big I was checking to see if I'd have a decent range
With the blower it didn't seem to change at all unless my foot was in it
It's somewhere in that range. Can't remember exactly.
