Check on-line with "Jegs", or www.summitracing.com they all have good quality replacement parts, even though they are performance places as well.

thanks for answer!
yeah i checked out Summti racing, good website!
i found alot of parts, but all to improve HP, or performance parts.
i'd like, for example to get a different camshaft for my Blazer, no OEM, but i think in this case, a new camshaft, with different perfomance, needs also different bearing, valves etc... to work good.
what do you think^
thanks again
Fabio

I know trying to find a 350 cubic inch,(5.7L), might be difficult in Italy, but that would be the best to rebuild and is a drop-in replacement for the 305 with power gains from stock. You should be able to get a decent cam,lifter ect kit from summitt for that. Jegs would also help. You want to go for the low end torque in my opinion. Get a cam,lifter, and intake kit from Summitt. Thay have them. Read the specs on those kits and go for what works for you. Don't forget to do a compression check to see if the lower end of your motor is in need of rebuilding also.(crank,bearings pistons,rings, rods, rod bearings ect.ect. ect.

maybe i found it!
what do you think?
i checked out 1.000.000 pages about engine rebuilding and so:
- my RPM range is 1700-2500, usually running 50KM and 90KM(60 mph)
- 1.84 valve (i read lift must be 25% ca of valve diameter so 0.460 ca)
- i need to rebuild my engine as original equipment, increasing power BUT NOT necessary, 'cause i think rebuilding engine as original my truck will run surely better than after almost 30 years.
so... i think "summit racing" has a good product for me.
i can't post link but if you can check our this number product to look it "COMP Cams 12-239-3"
what do you think!?
thanks!
