I want to put a 383 in my '77. This motor is strong and it runs great, but I want low end torque to rip the tires loose when I feel like it

i need to know if i should just look at another crate engine and swap the parts over or if this engine qualifies to install a stroker kit. It has no more than about 40k mi on it, and it doesn't burn oil or anything. the cost really makes a big deal to me, and i know it's cheaper to go with the kit, so that' what i'm leaning towards. if you agree this is the way i should go, can you recommend any affordable but not cheesy kits...i'm not saying i want the cheapest out there, but i don't need something that's about the price of a crate engine...

thanks

 

It would take about $5k to get a ZZ383/425, so I guess we'll look at about $3k for you. Right now Summit has an Eagle B13052, internally balanced kit on sale for $612. Machine shop will be about $800 for machine work and assembly. An Edlebrock top end kit has everything else you need, except the carb for around $1700. There's the $3k worth & that's probably good for 350-400 hp. The heads intake & carb could be sourced used, for 1/2 the price.

 

Cleaning and machining your block will be about as expensive as a new block from Summit/Jegs.

A seasoned block, machined and clearanced for the longer stroke is about $750 shipped to you door (2pc or 1pc rear main, your choice).

I found that the best deal is an assembled short block - you have to buy the rotating assembly anyways and if you buy the block from the same shop then you only pay like $100 more for an assembled and balanced short block....

Parts:
block (new) $700
block (your old block machined) $500-$700
block (used, machined) $700

rotating assembly $600-$1000 (cast stuff)

You can buy an assembled short block for $1600 shipped - search Ebay, there are several engine shops with good reputation: Theenginestore or Manrengines for example
