What would a 350 bored .060 like better?? I see that summit says that the 177 blower is for 350 or larger cubic inch motors? I see more 144 blowers being used than the 177 blower.Any advantages of one over the other.

Neither is that big, if it’s a choice between the 2 I don’t know why you would choose the 144 over the 177…

fit under the hood

Both are going to need a good size cowl, and if you don’t want that and are going to stick it through the hood you might as well go with a 6-71…

Spent too much and waited too long for the hood to cut it up !!

Well you better look at something else besides the old school roots blower then. As for the differences the 177 supports around 600 hp or so depending on your pulley ratios. The 144 supports 500 to 550 hp.

You might want to look into centrifugal superchargers or a custom eaton mounted on a fabricated bracket. There are acouple of members here sporting eatons on very nice setups. Course don't plan on that being a weekend bolt-on out of the box.

I wouldn't recommend getting serious with a 6-71 or larger without double keying the crankshaft first for peace of mind.

Ive got a 3" cowl hood already. Im not into having to fab stuff up to work. Ill slap the "old school" roots on there and be done. The price of a paxton or vortec isnt worth the price to me to pay and then have to make stuff work.

IMO I would think you will go thru a great deal of rigging up to get the roots to work perfectly with all the brackets anyways. Why not go for the gusto in power

bigger CFM rating, more air, more power and gives you room to grow=177

The roots doesnt have any brackets to worry about, its just like replacing the intake and adding a pulley.

A 177 is basicly 2" longer and 2" taller than a 144.......to get the same amount of boost out of a 144 to a 177 you will have to spin it faster, faster with a roots = more heat, more heat = less HP

go 144 and when you want more spray it

That's what I'll be doing with a 177 if work ever picks back up grr.

If you want a nice addon of power get the 144, especially for hood clearance if thats an issue (you still need higher than factory cowl with a 144). If clearance is not then get the 177 trust me you wont regret it, the second you put it on you will want to get a smaller pulley LOL. A blower becomes deadly with nitrous on it so there is always more. :-)
