BBF & F3

I’ve read thread of 632 & F3 at yellow bullet lets switch this to BBF & F3

Why don’t we see more of the BBF & F3 combinations? We know of Tim L, Eric D, Brand B; and we know there are a lot of Chevy Pro Mod and Q8 cars and there’s not that many guys running BBF in those classes to sale off their old NOS combo. But for the Ford Mustang guys to stepping up the power in the Outlaw Drag Radial and Limited Street classes trying to make 2500 plus hp and keeping it sealed with low maintenance. What combos are out there for BBF & F3 or twins to make 2000 - 3000hp; I’m tired of seeing the BBC & F3 setups in the mustangs.

What BBF block, bore, stroke, heads, etc…combos are out there that can make 2500 plus hp? Are we stuck with Chevy stuff??? Don’t get me wrong I am a fan of a fast machine…. You have to give credit when credit is do….

4.3 stroke
4.440 bore
A-head
twin 88mm turbo should do it

i would think an f3 131 or a 135 with 580 plus cubes and some a460 heads would support 2500 hp

it not that the ford stuff dont work it the fact that the chevy stuff is all over the place hell you can buy a set of piston and rods at the hardwear store. I have seen a stock block and crank and a set of scj and twin 88mm turbos run in the 6.88 at 205

I already have a f3 135 on a sbf. I see you guys are leaning toward the a460 heads; are they better than the Trickflow or the Bluethunders? Which block can 4.5 bore and still have good ring seal and keep the comp down around 9 to 1?

block look into the a460 block or the urlta block piston are most likey going to be custom and trickflow makes a ahead with a 10 bolt or a 18 bolt if you are going to be thuring a tone of boost at it i would look at the 18 bolt heads thats just me what kind of ets are you looking at and what chassis?

25.2 chassis and running in Outlaw Drag Radial (315) and Limited Street (29.5) classes; I would love to get into the 4.50s but 60s would be good at any given time and 70s on those shake down passes. On the blocks, where we talking steel or aluminum?

both block are steel

You're making a comparison involving money and availability. BBC parts are simply cheaper and more available. Also more selections. The BBF stuff is out there if you know where to find it and what to look for. It's just a matter of pride to have a BBF in a Mustang. I spent the extra money so I could keep it all Ford.

The Thor's are awesome heads! But they are considerably more expensive than a good set of 18bolt TFS A460's. C&C makes the best aluminum block!

How about 4.600 bore x 3.750 stroke and 9.400 deck. Heads are E-460's. Actually the heads are on the CNC currently at Performance Induction Specialties. Slowly the project is coming together.

Sounds interesting..

I have a 4.600 bore, 4.375 stroke aluminum block, A heads and we make 2300HP spinning the F3R-139 to 58,000rpm. That is with a blow-through C&S carb. We have plenty left!
