rebuild my 327 vs. crate engine
currently i amdebatingwhich option would bemost practical if I'm trying to pull approximately 400hp out of my car? can you get this from a 327?
there is nothing wrong with my 327 now;I'm just wanting more out of the engine!! i have priced some crates; buthow much could i anticipate spendingto rebuild my 327 to achieve the same performance as a crate?
i have heard that 327's are damn near indestructible and would love to keep it my car but just not sure on the $ approach.
any of you guys past experience and knowledge would be greatly appreciated
thank you,
Brian

IMO the 327 block can handle 400hp as can just about any pre-1973 small block. Also unless it is one of those Vett/SS 327's then it is nothing special. When I used to build circletrack motors all the builders wanted was 350 4 bolt and 400 SB with the 4 bolts. If you are really good at building motors you can do it cheaper and better then a crate motor. I have seen guys that thought they knew what they where doing spend a lot of cash and in the end not match the crate engine specs. I know I say this too much but If you had to ask the question chances are you would be better off with a crate motor. Crate motors today are a good value and could increase the value of a car.

Gorn, I would agree with your statements. If someone has the background/experience/skills then they could build a very nice 327 in the 400+ hp range (but I would want to start with a 4 bolt main block). If someone is lacking the skills, etc. and/or is going to have to "farm out" most of the work, then I think like you, that a crate motor is a far better option. And there are certainly many choices out there for crate motors, from mild to wild, depending on what you want.

RE: rebuild my 327 vs. crate engine
while ihave little to no experience on rebuilding engines; i would be having this done! i have what i feel is a reputable machinist and mechanic.
my thoughts are : i guess i will just need to see how much it will cost to rebuild vs. crate.
thanks for the insight guys!! what are some of the better choices to check on crates besides (summit/jegs)?

I had a friend with a Big Block Chevelle who knew afair amountabout motors he had a "Pro" build his motor. This "Pro" even had his own Dyno. They started with a 396 Big Block with 113K on it. $13,000 later he was kicking out 425HP and the motor would only reach 6400 RPMs. The guy said it was because Crane messed up the design of the cam, It was some kind of new design and it was floating the recomended valves spings. He can fix it but he wanted to give Crane some time to figure it out. LOL like the engineers at Crane can't get more the 425 HP out of a big block.
I showed himthis link http://www.jegs.com/webapp/wcs/store...56498_-1_10763
And told him Hot Rod got it 550 HPwith a total investment of less then 10K. I think I saw steam coming from his ears.
