I bought a book, trying to put together my budget for the '69 Mach I 351W rebuild. Book is "Ford Windsor, Small Block Performance."

On page 168 they talk about Vic Edelbrock's 351W street buildup. I thought it was great until I came on the fact that Vic used a 5.8L Lightning short block crate to build on.

I can gather all the parts he added, but I have no idea as to crank, rods and pistons used in this crate "bad boy."

Anyone give any help.

Hey, Nina, went to Tupelo Auto Zone to get a price on these parts and they've got a Grrl manager. Hot damn!

Do you know what year engine it was? Also what type of cam did they pick for the build up?

The engine is a "Ford racing crate 5.8L Lightning short block (PN M-6009-58)" Cam selected is [surprise!!] Edelbrock Performer RPM cam - 224 degrees duration intake and 234 exhaust at 0.050" Valve lift is 0.496" intake and 0.520" exhaust. Lobe separation is 110 degrees.

All quoted direct from the book.

Even with the "stock" bore and stroke, this puppy produced 409 hp and 411lb/ft of torque. I want to wag that tail.

I am trying to find out what comes with the crate motor for pistons, rings and crank to see what else I need to buy to make it as close as is possible.

Looked in 2000 catalog and they have a M-6009-D58 351W short block that can make 385HP. It says that with GT-40 heads it is a .030 over bore on a 2-bolt main block. Hypereutectic pistons creating an 8.8:1 compression ratio with 65 cc heads. Piston rings are plasma moly-filled steel. Says that the cam is not included and there is no mention as to what they used to get the 385hp.

Was looking at the M-6007-A351 385hp long block and it comes with the M-6049-X305 heads and the M-6250-A351 cam. They only say that the engine is custom built with the same quality controls as new production engine does. That?s not really saying much is it. I would think that the block, crank and rods are the regular stock parts with the rod bolts being the ones with the football type heads on them. The M-6250-A351 cam is a hydraulic flat tappet type with a duration of 236 int, 246 exh @ 0.05 and valve lift of 0.520? int, 0.538? exh.

A 5.8 is a 351w, and yes people have been putting them in 65's for decades. Uses the same mounts.

Ed,

Thanks for your time to research that for me. The heads on Edelbrocks have a slightly larger intake valve - 2.02 I believe. That is probably where some of the horsepower is coming from.

Hey, I'll take 385 HP.

The carb they are recommending is only 650 cfm. I had thought it should be more like a 750. I am only going to use it on the street and MAYBE some real amature speed events - i.e. slalom.

It's just a very slow day at work!

That 385hp create engine that Ford sells (or sold) came with a Victor Jr. intake and they used headers and a 780cfm Holley. Seems like a lot of HP out of an engine with 9.0:1 compression!

They have in there also a 362hp engine and all I see different is the Performer RPM intake and a M-6250-A332 cam
