is it rollerized?
can it be made rollerized easily? best to just buy a 96 head and go from there or does someone make a kit?

which computer is powering it? OBD I or II
Whats best for adding power? ok I've covered this one
Hyper, cast or forged pistons?
connecting rods a weak point?
compression stock? 9.0:1?
type of 5spd it has? there was 3 or 4 different types

dampner/flywheel going to help smooth out the motor abit or should I just get another motor and have it balanced/blueprinted.

weak points in the 4x4 system?
TTB keep it or toss it?

most durable highway/4x4ing suspension kit.
4" suspension lift. air bagging it useful? pro's con's?

thanks

I think I can help on some of these I had one for a few years.
its OBD I
The best thing to add power is to put a 351w in it
I'd bet good money the pistons are cast
5spd trans is a mazda M5OD r2, they are junk I put 3 in my old truck
The good news is the motors will run forever and ever and they have pretty good torque.

ok so I'll be looking to get a tko 500 swapped in.
Will probably look around for a 96 (hydraulic lifters) and have it built/balanced to go forced induction then. I happen to have a pair of turbos sitting around that may make some good use on this motor.

You might want to check out that forum for information on the 4.9L, plenty of good information and very knowledgeable people

yes it rollerized can be put in easy..if i was you i'd go with a older head no exhaust smog on the head the bolts are all the same just have to get the older bracket for the power steering thats it ...i have a 94 block with a 75 head on it intake carb ported im put out on the dyno 190....all stock sofar..

Where can you find a Roller cam and lifters for a 4.9l?

I know that the inline six never came from the factory with a roller cam. and I know that it is available as a special order item from places like Clay's. but why is it when i was looking through Summit Racing online today, they had factory replacement roller lifters? i couldn't find a factory replacement roller cam to go with them... IIRC the lifter bores are the same between the inline and the windsor blocks

A custom roller cam will be in the neighborhood of $800

Why put a roller cam in a 4.9L when you are not going to rev it high enough to see any benefits of it in a street driven application that will return enough results to be worthy of the dollar expenditure?

Seriously, get a good dual pattern cam with decent lift and replace the factory one and replace the factory timing gears with a Cloyes adjustable set.Install the cam advanced 4 degrees......maybe get a custom chip for it.
