Are you comfortable doing any engine work/assembly yourself?

My first recommendation would be to build it yourself and gain the knowledge and experience.If you don't want to go that route, my next option would have someone local that you can go talk to in person and build a relationship with. You also have some good engine builders up by you-

And there are some good builders down by me

I've heard good things about Woody and Rick. Also look at CHP. I would not buy a motor from Summit with cheap chinese parts that you have no idea who built them and what the specs are. You get what you pay for.

To answer your question yes, it can be very streetable. I did a very simple combo, 10.3:1, RNH custom hyd roller cam, AFR205, Super Victor with a 750cfm Holley that made 550HP/589TQ at 5800rpm with a 2" header on the engine dyno. If we would have been able to fit his 1.75" headers on I would have expected about 20 more hp and tq. We had over 400ftlbs of tq at 3000rpm. You can do the same thing EFI as well, just cant skim on parts, big cube motors need big parts.

If I can help let me know

Hey guys

My name is Matt I work here at ATK came across your post, and thought I could give a little input into what parts we use in the 408ci stroker part#HP21. No Chinese heads here we use Edelbrock Performer RPM heads and the rotating assemble is from Scat, we stick to the big name brands like MSD, Quick fuel, Melling to provide top quality engines. The street ability of the engine if tuned correctly will be a nice little lope at idle and great vacuum for all your power accessories. If you want more power we also offer part#HP81 408ci 480HP 495tq, with Dart pro 1 heads, little more of a street/strip engine than the HP21 so street ability is not as good.

If you guys have any other questions fill free to ask.

Back to the basic question, is a 408 street able? I see no reason why not. Didn't some old Firebirds come with a 400 as an option? 390 Mustangs? Sounds like fun to me.

He asked about a particular 408. Displacement doesn't dictate streetability without all the supporting parts as context.

That's a VERY Good thought about the supporting hardware! It could be the difference between a dog and a new tires each week. I am still fired up about the cubic inches in a decent weight block. Quote Tim Allen here - "AR AR AR AR!"
