Comp XE258 cam fits...

[zoomie]

have to be a roller block though right? so no good for me...

yeah it is for a roller block, you could always convert over, or pick up a 95 and up 351 block that is already a roller block from a truck or van

[gadget73]

302 and 351 cams are effectively the same. You can stick a 302 firing order cam in a 351 or vise-versa. Can't stick a roller cam in a non-roller block without the proper lifters though, and those aren't cheap. Many many flat tappet cams out there to choose from though.

I always thought that 351's used the HO firing order? Learn something new everyday I guess.

[Brown_Muscle]

they do, pretty sure he meant the "302 HO"...besides not much point in caming a lo po anyway...

[87gtVIC]

Ahh I didn't even think about that.

[mrltd]

looks like they would both work. The lift on the 264 would make both valves clear the same. It says the 264 is designed for 1.7 rockers... but using the 1.6 would keep clearance issues mute on the stock bottom.

Merc91: Did you have to put valve reliefs into the pistons?

There are TWO grinds. One for 1.6 rockers that has the 114* lobe seperation, and one for 1.7's that has the 112* lobe seperation.

the numbers in the name represent the intake duration the 258 is 258 int 264 ex an the 264 is 264/270

bot have 2 versions available. One for 1.6 and one for 1.7 rockers.

ah... an added bit of info there. I was looking mainly at the lift numbers.

Yeah, I dunno why they do multiple grinds of the same "name" cam.
I think they do it for most of the cams, I guess it's for people running the 1.7 RR's.

But that's what you have to look out for when you buy one of them....especially used

I meant that you can put a cam with the 289/302 firing order in a 351 The journals and lobe spacing and all that stuff is identical so physically the camshaft fits and will operate in the engine. The camshaft determines the firing order, the block doesn't matter. I have actually worked on a 351 that had a 302 cam in it. That was the motor that went in Natehawk's 85 Vic.

imo the HO uses the 351 firing order, also the 35 in the 35-510-8 part number denotes a 351 firing order, and 351 roller and 302 roller cams will fit either or, alot of lightning guys,and bronco guys use the HO cam to increase performance. matter of fact for all you 351 engine nuts out there there is a lightning shortblock for sale 250.. i think... let me go find it.

sorry bout the vids, i dropped the ball on that, I've been in school and work all day and a big pine blew over in the wind in the yard so i had to cut it all up.

The good news is I timed my 0-60 and its 7.6 seconds... compared to the 8.5ish with the same motor and stock stang cam+1.7's. And thats with a major slipping tranny at the shifts (the second shift being unhandily timed at 50mph to slow it down), and stock 4000RPM shift points, all the hunting gear, hockey gear, and 100LBs worth of subs and box, and a passenger! With the new tranny and just me in the car in a few months holding it to 5500RPM It's gunna be damn near 6 seconds, I'm a pretty happy kid!

thanks for all your help with this guys, I'll at least get an in-car vid up tomorrow nite.

[merc91]

and no flycut on the pistons, and yeh the compression ratio is pretty high, but the cylinder pressure is freekin high in this thing especially with that cam.
