After a few discussions with various people, I've decided to swap the idea of buying a 408W and go with a 347W instead. It's 50lbs less weight, it would fit under my OEM hood easier, and will be better suited for autocross.
I'm doing some research on which would be a better idea, buying a complete 347 or building one on some level. Here's what I've come up with, assuming I'm going to get it all done before I pull my current engine 302 out:
Building a short block:
Craigslist find for a good 302 roller engine - $300
Machining and prep for 347 - $500
Scat bottom end from Summit Racing - $1,750
Total ~ $2,550
Building a long block:
Adding AFR heads - $1,790
Adding Scorpion roller rockers - $355
Adding ARP head studs - $101
Total ~ $4,800
Building full engine:
Adding camshaft kit - $525
Adding oil pan - $70
Adding valve covers - $70
Adding Edelbrock RPM Air Gap intake - $287
Total ~ $5,750
Some will immediately say that this is not an exhaustive list of parts, and I will 100% agree. I am more convincing myself just to buy a complete engine the way I want it done (for the purpose of autocross and driving) rather than trying to eek out every penny and go the cheapest route.
Blueprint Engines offers a 347 with 415 hp / 415 torque for $4,800 (long block).
Prestige Motorsports has a couple 347 options between $6k - $6,600 for a long block.
I haven't built an engine in 25 years. I have torque wrenches, slide calipers, and socket / ratchet sets. No micrometers, etc. Could I muster through it? Yes. But I do like the fact that it comes with a warranty from a builder, with a dyno sheet.
