Im looking for a forum for small block Ford engines.
Any Help greatly appreciated

There are a lot of folks here that have built and raced SBFs for decades, EFI included. Bought my first 289 Mustang new in 1966, and have had both FEs and SBFs ever since. Boss 302, 351/400, 351Ws from 357-427CI. Y Blocks since 1962. Maybe your answers are available here. Joe-JDC

Like Joe said, some of us dabble with other Fords, including small blocks. My pump gas, hydraulic roller 347 SBF runs 10.0s at 133 mph, and is "all motor". So ask away, if nobody here knows, we will likely say so, unlike so many of the clueless responders on a lot of the facebook groups.

Same - built and broke a few 302s and several 351Cs. My backup motor is a 302 built in around 1997. Pretty good little hummer, about 300HP. 65~66 289 block, old TRW slugs and mid 90s ported Lighting heads. I luv it.

Rory428, you said a mouthful in this post.
There are forums dedicated to small block Fords and, unfortunately, many seem chock full of people DESPERATE to either tell you what they know, regardless of how wrong, or desperate to start an argument over the simplest thing......Like asking a basic question.
This forum does not cater to the small block but there are members here with PLENTY of small block knowledge and experience.

Agreed. Me too. Injected gas Boss 302 in a F.E.D., SCCA raced a 351W. Built a number of Ford, GM and Chrysler engines.
So, that all said, what are your questions
Btw, I'm the former (and only) moderator of the old Net' 54 SBF Forum for 15+ years until the site owner pulled the plug. Sorry to see it go as it had a wealth of SBF information.

Bob, did you ever race the FED with the injected Boss 302 at Mission Raceway back in the 70s? I took a photo of a FED with a stack injected Boss 302 at Mission , probably around 1973 or 74.
-
No Rory, not me. But we bought our rail from noted transmission builder Bob Rose of Chicago as a turn-key runner. Found out that famed builder R&B of Kenosha, WI build the chassis. It's possible Rose or even R&B took the car to Mission before we bought it in IIRC late 1976 or so. Had a C-4 worked to high heaven and ran only 2nd and 3rd gear.

I'll throw out a question to the brain-trust here.
I want to build a 347 for a replica vehicle build. Any suggestion as to a Ford block to use for the basis? I read the Boss blocks were the best choice. Is that correct? If so, is there a good second choice as rare as they are?

If you're wanting to use a factory block, the Boss 302 block would be my first choice, followed by a Mexican 302 block. Third choice would be any of the late 60's/early 70's "normal" blocks.
Boss blocks are pretty beefy:

That block ended up being the foundation for a 302 Tunnel Port build:

Agree with Brent (as usual) but will add the very best is the relatively new Boss 302 block. Given, that is, you have deep pockets!

The block above is a factory B2 block.
I don't really care for the Motorsports block. I'd rather have a Dart. With the Dart, you get billet main caps, etc.

Fixed it.

Didn't know the Dart has billet main caps.
-
Bob, my 347 SBF has a Dart SHP block, and it has billet main caps. Now, the cheapest Dart SB Chevy blocks have cast iron caps, but I am pretty sure all models of SB Ford Dart blocks have bilet caps.

How good or bad is a later 5.0 Rollercam block?
The last 302 i built had a mexican truckblock
was probably out of a van looking at the transdipstick
so you know where you can find one
-
For strength, the later 5.0 hydraulic roller blocks are about the weakest , but fine for mild, or even moderate racing. My 331 SBF stock Hyd. roller 5.0 block lasted for 6 years of 10 second 1/4 miles, with a clutch, launching at highish RPM, with a 28 oz 3.25" stroker crank, before it split thru the mani webbing.I caught it in time, and "reblocked" all the same guts in a early 70s 302 block and ran it for 3 more years before I sold it, and got my Dart block 347 in the car.

Brent, do all the World Product SBF blocks have provisions for 6 head bolts per cylinder? And if so, are they 7/16" or 1/2"? My Dart SHP block has only 4 bolts per cylinder, although they are 1/2"
-
Yes, they do. The outside perimeter bolts are not 1/2". It's a nice feature, but there's only 1-2 cylinder heads that have provisions to be bolted down like that.

It's a craps shoot. Sometimes they go a long time, sometimes they split immediately. I've had one, built into a 540hp 347, that's been in the customer's bracket car since about 2010. Been freshened up once. It's survived hundreds of passes, with 5500 rpm clutch drops and 7000 rpm shifts.
This little baby is also a later model Explorer roller block, 311 cubic inches, 540 hp @ 7400 rpm.

Blykins just curious, you that have built a few sbf what hp
do you guess i had in that. 030 over flatops ,10.5 CR
Ported milled 66 289HP heads with 1.90 1.6 valves. 308 deg/ 510 lift cam
think it vas 262 at .050 lift edelbrock performer rpm 650 dp holley
Hooker super comp headers, good machine jobs. 375??

That's a whole lot of cam for the displacement, head, and intake, I would think 375 would be on the high side.
-
Yes, if the .050 is indeed 262, that is way to much cam. That cam could get you 8k rpm, if the heads are big enough. You should be able to get 375 hp with a 232 cam.
The 289HP heads don't have any flow advantage, unported, they just have spring seats and screw in studs. Porting isn't easy on them either. Stock they flow about 165 and the best porters can't get above 240 cfm. I had a set of C6 heads and after quite a while porting on the intake, schooled by a pro, I was only able to get 196 cfm with a 1.90 valve, good for close to 400 hp.
A EMC competitor, got 2nd place, in the last EMC with 294 ci, 235 cfm heads, dual plane intake and a 242@.050 roller cam for 440 hp @ 7.2k.

Yes probably, In those times chosing parts was like ... as far down and to the right in the catalog was the best parts
only you that is old enough to have purchades from a catalog understand what i saying ;D
And it was a Camdynamics catalog so you know how long ago that was. whatever hapened to Cam dynamics?
Must have went under in the late80s.

Im abit unsure about that 262 was about 40 years ago, sound wrong to 308 adv 242 sounds more realistic remember redline 7200 anyway
