302 Rebuild
I am going to be rebuilding my 302 in my pick up, and i'm wondering what i can do to it to beef up the performance on it. One thing i'm going to do is bore it 30 over but i would also like to perform some other mods to it. What are some things you folks would recommend i do for performance. I realize there are probably several things i can do, but some suggestions would be great.

You could get a high torque cam if you use it for pulling or maybe a hot street cam if you like to race a little, a port and polish job on the intake and exhaust ports, a nice four barrel edelbrock performer intake a 550 holley vacuum secondary up top, a set of headers (not Cheap) and some flat top pistons (make sure the compression ration does not go above 9.5 to 1 or you will be very unimpressed.)
Just my .02

PS also if you are made of money you could also buy a 347 stroker kit

Thanks Steve, i'm going to check out the four barrel intake tonight. so far what i'm going to do is port and polish the exhaust ports and the heads and install a factory roller cam out of a mustang 5.0, thinking about a new throttle body too.

Depends on the year of your block. Someone here knows the exact year but sometime in the late 80's the blocks used in trucks were roller cam blocks but only had the flat tappet cam/lifters installed. In this case there are conversion kits to make the change-over.

Hmmm. Maybe so on the no-roller block. I've heard it mentioned more than once on here that they used what I described in the 302 trucks starting in 88. Check this threadhttps://www.ford-trucks.com/forums/s...t=roller+block DeGideo talks of such a thing. Also do a search on roller blocks in this forum. I know there's others that make reference to it. If nothing else send DeGideo a personal message thru this site and ask him to verify for you.

first have it balanced and some blueprint work done at the machine shop. This makes the bottom end almost bullet proof in a street aplication. Then you can worry about bolting on the horsepower. First you must start with a good foundation.

my 90 5.0 is a flat tappet block and has the shorter lifter journals and no taped holes under the intake manifold for the roller lifter retainer/guides
i do however have a 89 Mustang GT 5.0 HO roller block and GT40 heads waiting for some warmer weather to be installed in my truck.

From what I've been led to beleive is that these era blocks could have the retainer bosses tapped at a machine shop and utilize the OE type roller-lifter units vs. the need for the retro lifter units needed for the older blocks. The cost of machining should be minimal. The retro's would be an option too as would just finding a fully settup roller block.
