3500 solid cam

[SappySE107]

Dynomation says that cam is about 50 hp better than stock at the crank. If you get it tuned, that should be very potent on an otherwise stock 3500.

My plans are to use this cam with unported heads and intake. Have the springs done and get the pistons cut for the valves. I just want to see what a stock 3500 can do with a big cam. I know this cam is not the best option but it's something I already have. Any advise on power it will make with a good tune.

or I be you could machine an insert for the stock lifter to turn it into a solid.

The lifters being used in this setup were designed for the 60 degree block.

FActory 3500 anti-rotation guideplates can be removed since these Crane lifters have the connecting bars between the two to keep from rotating.

109 LSA isn't bad, I have one in a 3.1 that is 99.5 lsa. You will loose a lot of static compression however, so anything you can do to bump it up will help. Larry

crane 25523-12 is the part number on the lifters.

veekuusi is using SBC lifters iirc...

Solid roller or not you still need oil to go up to the rocker, holes don't line up rockers get no oil... But I guess you guys have more info about this engine he's working with than I do since form what he's posted I'm not gathering what you guys are saying so I'll just step back from this thread.

you're very right, but there's so many aftermarket solid rollers available for the SBC, that I'm sure there's one with the oil hole int he right spot, no need to step out you bring valid points to the table.

It depends on the lifter but these may have the oiling holes lower on the body.


It's the LT/LS roller lifters that don't work in the gen 3 blocks, i've never tried the SBC flat tappets or mechanical though.

Last time I read a thread about someone wanting to use newer SBC lifters in a 3500 it's not possible because the oil holes don't line up. Maybe I'm wrong but I remember that being a question in a thread.

this is a solid roller though, I bet they would work with custom guide bars..

What?

I'd say they know exactly what works in the 60* V6.

SBC lifters have been used in 660 since the '80's. It was actually a recommended upgrade directly from GM Performance division, for heavy duty and racing use.

SBC valve springs have also been used and recommended for the same reasons, and for as long.

The 660 actually shares a number of component dimensions with the SBC, like the lifter diameter, crank snout diameter, early cam bolt patterns, Valve spring sizes are close, cam bearing diameter, though the width is different.

A bit odd that its a Lunati 60 degree v6 cam but they have recommendations on SBC lifters and SBC non conical springs, seems like they don't know what works with the 60 degree engine. Also the 1.5 ratio is wrong, since roller 60 degree setups had 1.6 ratio rockers.

Nope, it's a gen1/2 3 bolt style cam. Old school so the double roller will work.


the gen 1 chain is HUGE compared to the later ones, I've got a comparison pic somewhere.

How did you guys figure that out... I didn't see that info posted anywhere.
