Questions & Answers

How do you know if these will work with SBF 302HO motors?

The threads are 5/16 coarse rh so they should work for that motor if that's the size.

How do you know if these will ?

No, but I use them on my 2 350"s and my 454 and my headers are fine with them

Can you tell me what size wrench I need for the external hex?

The inside uses a 3/16 Allen wrench socket for the outside and an 11mm box for the outside.

The item I'm looking for fits my 86 Ford F150 with a 4 cylinder engine. Why does this motor have a 9300 horsepower rating?

There seems to be a Gen1 Small Block Chevy with headers that will fit it. The threads on the bolts don't look like Ford ones, so I'm not sure if they are Ford threads.

There is a chance that your set will work

3/5

Those are the ones I have. The situation is not There must have been an error in my As I threaded in 4 out of 8 hex head bolts I've installed so far, I noticed their heads were misaligned, giving the appearance of a wobble. After all of the holes were drilled, the Safety cable could not be inserted because there were metal burrs. I am not happy with this. The Amazon drop off is far from where I live, so I don't want to dicker about the return.

Working for them was a success

5/5

Everything is fine for me. Although I knew that there would be a small hole to run the wire through once the motor was inside the truck, I didn't anticipate it would be so bad.

3/8 to 3 There is a 16-course thread, not a 5/16-course thread

5/5

These bolts are 3/8-inch long, and come in a pack of 12 I installed these on the 1997 Pontiac Trans Am 5. They fit perfectly. The 7L LT1 set is very nice.

I like this bolt set

5/5

It's a good product. One complaint is that there are not enough to do both sides of a V8 in one pack. Two sets need to be ordered.

I give it five stars

5/5

Despite not using them, these five stars are based on how well they performed as described.

It is 3/8 and not 5/16

3/5

They are actually 3/8 and will not fit on a 5/16, which is why they aren't 5/16. Designed for two magnum magnums.

These bolts are referred to as "Solid

5/5

". It's a simple product but it works! I was unsure of purchasing such a simple device but I love it! bolts do not loosen as a result of the safety wire. Another set would be a great addition to my hot rod if I had one!.
