Replacing internals for performance and rebuild

Re: Replacing internals for performance and rebuild

you're calling an iron block weak? lol If ya say so

I am calling a iron block, like mine which was bored out, weaker then a stock bore iron 3.8.. and you dont think iron blocks crack or break?? How come a stock block 5.0 mustang pushing 500 or more HP with a fully built motor breaks blocks?? They are iron.. I have seen 2 3.8 GM motors crack the block.. One was a fully built GTP bored out, and the other was a 10 second GN.. Will it happen to every motor?? No..

thats facorty defect then...... any block in any car could have that

mine is borde .020 over and its fine

many blocks are and they are all fine

true, but a car that is all top end with a broken con-rod isnt going to make any hp.

unless your reving over 7000 RPM your not goign to brake a stock con rod, stock ones are in the 9's

Re: Replacing internals for performance and rebuild

stock ones aren't in the 9's, stock l67 and l32 ones are in the 9's

good try but ZZP has a stock L36 bottom end in the 9's

really, didn't know that, I thought theirs had the l67 and intense had the l32 rods

I agree.. stock connecting rods are pretty stout!! Now the stock pistons break.. I broke one with 313rwhp and 433rwtq!! But the stock bottom end lasted 2 years on the bottle and 65 bottles through it!!

Re: Replacing internals for performance and rebuild

stock pistons are aluminum right? I should be able to bend it back right?

Re: Replacing internals for performance and rebuild

How come no one has brought up the transmission yet? sure you can run it into the 11's but with a stock transmission and TC, you arent going anywhere but the back end of a tow truck. And you will be there in half the time with manual.

I dont think the guy who started this thread knew what he was getting into...

Re: Replacing internals for performance and rebuild

I'm not saying forged parts are a waste of money by any means. In 1998silverbirds case, the lighter pistons freed up some hp and allowed him to rev faster which was a benefit. The extra cost of the forged parts were worth the money to him. However if I'm going to build a slightly modified street engine making a few ponies more than stock just to go cruising, I think the money could be spent elsewhere where it could do more good like a free flowing exhaust. I feel forged parts would be overkill here.

I'm going to rebuild my 350 in my 69 camaro at the end of the summer. I don't live near a track, so its strictly a street car. Right now it has a stock cast crank, stock rods, cast pistons with crappy 76cc iron heads. I'm going to put on a set of Trickflow 62cc aluminum heads and a new cam with .480/.494 lift and 228/234 duration at .050. I should be making around 425-450 hp depending on whether or not I stroke it. Even with this upgrade, a cast crank would still handle the power so upgrading to 4340 forged crank is overkill unless I plan to use Nos etc. In my situation, I don't need high dollar forged 4340 cranks since that would be overkill. From a cost perspective, a cast crank cost around 200 and forged cranks range anywhere from 500 to a couple of grand. I can't see spending over $1000-1500 for a lunati or crower crank in my situation, but to each his own. Some people are willing to use the best no matter what and thats fine too.
