Re: ??? on blazer buildup
if you have good oil pressure and the truck does not burn oil, i would not bother with the bottom end rebuild. if it is in sound shape, you don't need to build it up to make the power you are looking for. a new cam and top end will do great.
you can get world product racing heads for the same cost as having your old ones rebuilt in many cases. go for the 170 intake runner, 202 160 valves, cast heads. oh, 64 cc chamber. that is at the top end of streetabe and will not cause you any issues. assuming you have a flat top piston, you are gonna get 10:1 or so depending on the cam. which will run fine. they are about a grand, but they are new.
summit racing also has some stock replacements, for just under $700. not as good as a world head, but still just fine. they are an improvement over your stockers for sure. you make lots of power with heads, but also can spend lots of $$$$.
for your carb and intake i like edelbrock products. they are not the best out there, but they work and they are cheep. plus, easy to work with for people who don't know the ins and outs of holly and other high end carbs. you want the vacuum secondary 600 or 650 cfm carb. those work great with a performer intake. again, not to over the top and will work good for you. you might need a hire volume fuel pump, i dont know what carb you have stock.
headers, good investment as well. plus a good exhaust system. you can burn your starter up tho with headers, but if you get a good racing starter it is not an issue.
while you are in there, get a brand new HEI. they are around $100 and will replace any old or bad parts.
that motor above, depending on what you do, will make an honest 300 hp.
that takes care of the motor. just a quick over view. your best bet is to look around the internet and a summit racing catalog. i like summit, i use them and never had a problem even when i sent stuff back.
if you are doing a lift i know about those too. same with axles, i am guessing you have a dana 44 front and 10 or 12 bolt rear. both are good, and with upgrades are great.
tools you will need
2. 4 1/2 grinder
3. good braker bar and cheater pipe
4. jacks and jackstands
5. motor crane. worth the money, which is not that much
6. big hammer
7. pry bars
come back with any questions, ill try and help you out.
