im ordering a hydrolic roller 350 from advance auto parts for $1069 which i think is pretty decent...$100 more for 3 yr unlimited mile warrenty or the normal is 1 year unlimited...but anyways what kinda power can i expect with a performer rpm intake and a holley 600 carb.....for now i am gonna leave the stock cam and stuff.....i dont know exactly what heads it has but it says its the replacement for camaros and caprices....any rough estimates...will it feel faster than the cammed 305?

 

anybody

 

I think you just bought yourself a piece of junk for your money and then spent $100 extra for a warrany. You will need more then you mentioned to get about 150/ 165 HP if your lucky. Also a 305 TPI will be faster in my opinion

 

If it's GM part number 12513151 you got, that's a pretty good deal. Check my sig for mods and times. I should be in the high 14's when I get my transmission rebuilt and take it back to the track. BTW with the stock intake manifold I pulled two car lengths on a freshly rebuilt stock 305 TPI IROC my friend was driving. The heads on it should be swirl port heads and the cam it has is designed for low-end torque. Pace Performance has more details about the engine in their catalog.

If you read the Post you will see he is buying it from Advance Auto Parts. It is not a GM crate like you quote it a cheap replacement rebuild.

 

My apologies, I was thinking of a different company that sells GM crate engines. :shrug:

 

and what is your suggestion djp.....ima high schooler on a limited budget...i ahvent bought it yet

 

Since your on a limited buget don't spend it on junk for one. Check out the GM crate engine for about the same amount of money. Will not give you screaming performance, but it is a good base to build on. Or save your money for a better upgrade if time is not a factor. Check out www.paceperformance.com

 

i think what ima do first is goto advance...find out who they get thier engines from....call them....up...ask about heads and cam specs...fuel pump provisions...that kinda stuff....and find out what parts they use in their engines

 

another question....would you guys go for a flat tappet prior 86 motor or a hydraulic roller 86 up motor...........is one block stronger than the other?.......

 

Do yourself a favor and get the 350 HO Vortec Crate from Pace or Scoggin.....For about $2,000 you can get the short block (everything minus intake and exhaust) and YOU WILL BE VERY HAPPY WITH IT....TRUST ME!!!!

If still too much....then get you a Goodwrench 350 for about $1,200 to $1,500

hope this helps

Later

 

The later blocks aren't as strong as the older blocks from the 70's, but that isn't a factor until you get into the big hp numbers.

The parts store motors are cheap, and I considered getting one a long time ago. Everyone I spoke with (repair shops, machinists, etc) said that they were crap. Their rebuilding process is far from complete. Their tolerances and clearances are also much wider than they should be. I've heard of cases where the engine is put in, and it spins a bearing in the shop's parking lot. For a stock rebuild, they barely pass. For performance, no way. Even if it did, the warranties don't allow you to modify anything anyway.

I would save up, and get a GM or other quality crate motor, a good used engine from the junkyard (that can be rebuilt right, if it needs it), or a used 350 block and engine kit. The parts motors look like a great deal, but when they break they end up costing more than doing it right the first time.

 

who carrys the gm goodwrench motors for the cheapest price
