Hey guys, me again, i want to rebuild my old 350 block this winter, and was looking for some suggestions as to what to buy in terms of a build. im on a 2000$ budget (not including machining costs for the block). The block is a 1 piece rear main seal, 4 bolt. im looking to get into the 375-400 HP range, i think im going with procomp aluminum heads, but as far as any of the other parts go im still unsure as to what would be best. Also, would it be better to go with an EFI setup?

all help/suggestions appreciated!

end use... ???  
street car.. truck.. suv...
street strip...
strip only..
do you care about MPG..  over break neck power..

its more expensive to go with fuel injection to reach the same power range in most cases...

there are forged steel 350 cranks for the One piece rear main seal blocks..  usually out of stick shift trucks ..

this is only the beginning ...

what transmission.. what gear ratio.. what rear tire size...


and.. what parts do you already have??????

carbs.. intake... heads...  exhaust... distributors...  

make a list.. with model numbers if possible.. you could have enough stuff to built it for less..

the only thing i have at the moment is the 350 block, id like to build the engine for street use, but i want something very aggressive, id love to put a blower on it (the 2000$ budget is for the engine only, i could swing a blower on top of that). i was thinking 3.73 gears? its for a 1974 chevy nova with stock size tires, id like to go wider, but id keep the dia. stock. Id also buy whatever trans is recommended for this build, but atm i have a th350 i was going to rebuild, could this be rebuilt for an aggressive street application? i have a few edelbrock 600 cfm and 650 cfm carbs, as well as a holley double pumper 750 cfm carb in need of rebuild, as well as a holley 650 cfm carb thats 2 months old.

2K could get a decent short block

2K for a long block and you'd better be looking for another set of parts to replace it when you destroy it with power adders

starting from basically scratch, a big block might be the better route to take in the long run?

Hi there,
 Stick to the Holley 2 months old 650cfm..
 There are a zillion ways to get that baby
 working to 375 hp if you have the comp/cam/
 heads etc to match.. One problamo...Budgets
 rarely work without lots of help down the line.
 You only get for what you pay for.
 When plan "A" fails then resort to plan "B"..
  Australian Army saying of yesteryear..
 Good luck..

The th350 can be built to handle all that 350 could put out. It is not cheap however. There was a 55 Chevy Pro street car running mid 6s in the 1/4 with one.
I would estimate the cost of your motor to be in the 4000 dollar price range in order to get the power you want. With stock tires you will have a lot of wheel spin. I would consider drag radials. I ran them on my 95 Camaro which had about 350hp and the wheel spin was not too bad. With stock tires first gear was all tire spin.
