all of my local shops can't find one, i don't wanna go with flat tappet if i can avoid it, and i definatly want to avoid a mechanical cam.

anyone know of one?

 

You can have a custom one ground from Crane or Comp Cams... the stock '94+ 3100/3400s have roller cams...

The problem is in the oiling of them, though! From what I understand, using the stock roller lifters will cause you to starve the crank of oil.

 

Flat tappet is the way to go, rolelr cam setups weren't intended for these motors. Stick with a flat tappet, it's the safest route.

 

This is not true and a myth at best, at least involving mechanical roller cams. I looked into this and about 20 different people over at 60degreeV6.com are running mechanic roller cams without any problems. Go over there and ask.

 

Stock roller lifters are not mechanical, though.

 

to what purpose though? Motor was designed to runa a flat tappet, run a flat tappet. I know it's been done, but why?

 

A roller cam can make more power, as you have have steeper cam lobes - think of the lobes on a graph - you have more 'area under the curve' with a roller camshaft.

Not to mention less friction losses

 

ok i'm using a hi flow oil pump for my new motor. everyones been telling me to run the crane 2030 cam, sound like a good idea? if its better to run a flat tappet then i'll run one.

 

it's mainly how the blocks designed that makes it so crappy to run roller lifters. If you can score the "somewhat pricey" aluminum gmpp 60* block, this oiling issue has been taken care of. I also think teh gen II/gen III fwd blocks have this improved oiling also.

 

It's not "better" to run a flat tappet... it's just a bit of a PITA to convert to roller. The reduced friction of a roller setup will free up power regardless of your cam profile.

 

Project 85 is right... but hey, a flat tappet works fine for us!

Also, the FWD blocks will not bolt down to the RWD platform. I am debating whether or not to build an adapter, and sell them, too.

 

These guys,

Sell a "conversion kit" to use a FWD engine in a RWD application. their specialty is V6 conversions for the MGB. They like to use T5s. Not sure if it is a special bellhousing or an adaptor. might work in a 3rd gen camaro.

There are no oil issues with a roller cam on the normal 2.8, 3.1, or 3.4 blocks. I verified this over on 60degreev6.

 

I'm going to throw the stock 3100 roller setup I have, into the 2.8 rwd block - I'm going to repair the bottom end, but I'll probably end up starving the main bearings @ 6000 rpm. That's bad

 

Solid roller, yes. Hydraulic roller, no.

 

Listen, I am only passing along information. I was told by numerous people at that site that neither the solid or hydraulic would cause any oiling problems. Many of the respondents were running either hydraulic or solid roller setups without any problems on their 60* V6s.
