Guys I need help deciding to keep my built 355 in my truck or swap a 5.3 and sell I would probably add a cam and other stuff down the road

 

5.3 will make more power easier

 

Yep, hate to say it, cuz I love the old gen sbc, but the 5.3 in stock form will support/handle more HP then a built 355, will do it for alot less.

 

Thanks for the response what am I looking at cost wise to swap a 5.3 I can get everything harness intake and everything for like 900-1000 also is getting hooked up to a 700r4 what's the cost?

 

Its all in the heads. Put great flowing heads on a 355 short block and it will run as good as a LS engine. Then you get to a point where your stock SBC block will start to flex or even crack. The LS block is a deep skirt design and is much more rigid overall. The LS engines do package nice and have a pretty nice intake and injection setup right from the factory as well. I still prefer a nice small block though.

What have you got now for an engine? My 95 was just a tired 350 with ported vortec heads and a LT4 hot cam with a single plane high rise 2 barrel intake and a 454 TBI throttle body. It never did run quite right with the antiquated fuel injection system but on the days it was running good it ran strong and the sound was incredible. No LS engine will ever sound that good.

 

I have the 355 right now in the truck it runs good and has very low miles on it sounds good too just want some more power

 

build you a nice LS and enjoy.

 

Your going to spend alot of money on sbc heads to get the power a cammed 5.3 will make

 

I was a die hard SBC, BBC guy and you will never get me to build another one again.
its ALOT easier and cheaper to build a LS
my little 325ci LS makes more power then my dads cammed with head work 427ci big block.
he is blown away just how easy it is to make power out of these little things
