I was recently told that there are early model truck blocks with 4 bolt mains. I was under the beleive that the only 4 bolt main blocks were the SCJ and Boss blocks. Is this true?

Thanks,

James

192.223.186.84 Why all the hub-bub about 4-bolt blocks
No score for this post August 17 2001, 12:10 PM

With the availability of main cap girdles and/or Milodon's Splayed 4-bolt main caps, any 2-bolt block can be setup to as strong, if not stronger, than than a stock 4-bolt block....Oh Hell, go for the gusto will a Splayed caps and a girdle, and then juice the hell out of her.

Now, if a 4-bolt block has thicker webbing, then I stand corrected. Please let me know if this is the case.

Best Regards,

The factory 4 bolt blocks are based on machined web blocks, there is more material in these blocks around the crank webbing than the cast web block. I've done 4 bolt conversions on both types.

I am sitting on 4 of these blocks right now. Other than the taller deck height they are a match for the SCJ. Check out "High Performance Ford Engine Parts Interchange" (S-A Design) by George Reid if you need to see it in print by a known authority. I will stay alone if I can score these blocks for almost nothing and laughat the croud of people jack up the price of CJ/SCJ blocks.

Just curious if you would be interested in selling one of those blocks. What would need to be done to compensate to the extra deck height.

What trucks did these blocks usually show up in.

Thanks,
James

It will be like capturing bigfoot. I have the "Ford Parts Interchange" and the guy says these 4-bolt main truck blocks are very plentiful. If that's the case I must be looking in all the wrong places because I can't seem to find one and haven't ever seen a picture of one.

That's why you'll notice I never flat out said he was wrong. I've seen Ford do alot of crazy stuff, so anything is possible. What I'm asking is if he does find one to take a photo of it because alot of people would sure be interested in seeing it. I sure would not be dissapointed if it were true. However the book says not only that these 4-bolt main truck blocks exist, but that they are plentiful. I know at least part of that statement is false. If they do exist they sure as heck aren't plentiful. You'd think on a forum that specializes in 385 series engines that somebody would at least be able to produce a photo of one of these blocks and that's what I'm asking for here.

Is it possible these are 429 Blocks out of heavy duty trucks? Those use a different rod length and steel cranks. I'm not at work, so i can't verify this.

I think these 4 bolt blocks can be found in medium and heavy duty trucks such as the F-700 with the 429 in it, not to be confused with the 370 [same family]

63.25.254.82 Must be from a 2 or 2.5 ton big truck application...
No score for this post August 16 2001, 10:53 PM

If they do exhist, they would have been used in the same applications that you previousely found the "FT" block (361-391) engines which were a heavy-duty truck version of the FE.
It's hard to beleive (yet possible) that so many of us have overlooked these engines, especially for a stroker application.
How much taller is this elusive engine's deck?
Maybe there are other reasons that racers are not using them, like journal size etc.

205.242.224.202 George Reids book
No score for this post August 16 2001, 11:45 PM

George Reid is a known authority of mis-information. His book is so full of errors that it should not be used as an accurate resource on Ford engines. He claims in several places that the standard 429 came with a spreadbore quadrajet carb. One of his best screw ups is the pics. of what he claims are Boss 302 heads on page 45. One head is a 429 head and one is a 351C head. Page 112 his CJ head has no guide plates and small ports. This is the only reference you will find on truck blocks having 4 bolt mains and considering how many other claims he is wrong on I don't believe it. Of course a good pic. would change my mind.

216.209.119.113 misinformation
No score for this post December 15 2001, 2:32 PM

You are right there is a lot of misinformation out there. Fact is , in Canada at least the quad carb was a factory piece on many a 429 and 460 in 1973, 74, and 75 However not all came that way, some had the autolite junk, and some had a holley. Marine engines here, came with the quad, like forever.
I have yet to see a publication that actually has any true , relevent, or consistant data on these engines. Especially on the head data, or deck heights. considering that they were interchanged into the mid 70's.
