I'm finally putting together an engine for my barracuda or to possibly sell the engine outright. It will be a street/strip 421" small block that should end up around 11.3 to 1 and run on pump premium. I have a couple of cams to choose from. (1) flat tappet 260 -264 @ .050 with .640" lift (2) solid roller 260 - 266 @.050 with .670" lift. Both have 108 LS. I have all of the additional parts to put either cam in it. For resale purposes, would you pay extra if it had a roller in it over the flat tappet?

To add to that Rod the switch from a solid lifter cam to a roller costs a lot of money. If you spend 700-800 for better springs, cam, roller lifters, better push rods and everything else its hard to recoup your added costs. Lots of guys like myself like to pick the parts we want in a build.

Depends on the rest of the combo, is it going to be borderline ready to split the block already? If it is going to make too much power for a stock block then no, however if it is an aftermarket block then probably yes. It just kind of depends on the rest of the set up if it is worth it or not.

On another subject... Have you been able to keep 4.25 360 main cranks in stock lately? I want one but I got to sell my 4 inch stuff, don't want to sell the 4 inch stuff if I can not get the 4.25.

If you are trying to sell the build keep it as cheap as possible because we all know Mopar people are cheap.

If it's a short block sell it without any cam, if you want to sell a long block pan to carb I would do the FT.

It seems all of you are thinking the same way I am. There really is no return on the roller investment.

Dave, I have around 10 in stock currently.

Me personally, when I buy a non running, used motor with a FT cam, I just assume the cam will be flat, plus I am going to change it anyway. And with a used roller motor, I assume the lifters will be worn out or junk..........Now, if you are going to sell the motor as "new" and ready to go, I would rather have the roller. NOT a FT fan here. Don't see the point.

Roller if you use good lifters, Crower, Morrell or equivalent.

Comps will go in the trash.

Career best 8.02 @ 169 at 3050# and 10" tires small block power.

Use the cheapest stuff you use,Brad is 100% right and if you get half of what you paid it'll be a success.

That's right. On a good day you can hope to recover 60% of your investment, you'd lose hundreds with the roller, even though that's the best choice.

Rod,
Bring the roller set up over and test it in my small block and see what it gains you. My guess is very little for a lot of $$$$
Its amazing how so many people fear flat tappet camshafts.

I'd like to see that, say a mild cam in the 580 to 600 lift range and maybe the FT gets 1.6 rockers.

I'm going to freshen my pump 93 408 over the winter and considered going to a roller. The current cam is a 260/264 @ .050 flat solid and has gone 6.57 with a 1.38 60' best and 6.70, 1.40 in street trim at 3260#. The roller conversion was going to cost $1400. I don't see the small gain in a street/strip engine like mine being worth the costs.

Instead of spending the money on a roller I'll have some head work done and change pistons to get the compression up from 10.9-1 to around 11.4-1.

Has nothing to do with FEAR of a flat tappet cam for me. I just don't want one and see no purpose in it. With the new hydraulic grinds, hydraulic rollers and solid rollers available now, a flat tappet just has no place for anything I choose to do

I had a hyd flat in my 416 but after seeing this build I copy'd the cam and dropped in a set of his lifters. Haven't run it yet but I liked the numbers he made. I had 500 HP with the 292H Comp and the motor was perfectly happy spinning 7000. Voodoo 60434 in now.
