Re: Motor swap
Well, without knowing what you have now I'm just making assumptions. The possibilities are endless, it just depends on how much you want to spend. But, just some general guidelines would be:
1) Stock crate 350 would be just fine. 2) You can spend a little extra on heads, headers, carb, intake etc... and make some good power in the 350. 3) After that, you're looking at a stroker 383. 4) The next step would be a big block.

Re: Motor swap
Right now I have a 305, would it be cheaper just to buy the block and all accessories separate and put it together myself or just buy the complete motor as is?

Re: Motor swap
What's the best fitting engine? Foolish child. The biggest engine you can afford, of course!

Re: Motor swap
No replacement for displacement, cubic inches or cubic dollars... yada yada....
as mentioned 383 stroker best bang for the buck without doubt. |

another good thing to consider is what you are going to be doing with the truck-daily driver-show truck-weekend cruiser-drag truck. there is a great engine for each of these applications, but many do not economically cross over. Best of luck. Quote:
I am in this boat. I love LS motors. Lots of power, reliable and decent gas mileage.

Re: Motor swap
The best choice is the one that fits your budget. An LS is a great choice that you won't regret. Good power, great economy and everyone has parts!

As far as external physical size, a 5.3 or 6.0 are going to be the same. It's the internal displacement that's different. |

Re: Motor swap
5.3 with a LS6 cam swapped in and still save a $1000 over the 6.0
