Here are some fun numbers
500÷350= 1.43 hp per ci
600÷418= 1.435 hp per ci
400÷318= 1.26 hp per ci
400÷340= 1.18 hp per ci
390÷345= 1.13 hp per ci

Factory v-8 engines have been making over a hp per ci for along time. And 600hp 418 stroker's have been verified. 390hp 345 Hemi's out of the factory in ram trucks

Part of the problem is we all have different ideas of what streetable is, for some as long as they take it to the local spot and back and lay a little rubber it's a street engine. To me .75-1:1 hp per cid (239-318 hp for a 318) can be a very streetable turn the key go anywhere without worry, 1-1.3:1 (318-413hp for a 318) is street strip built engine needing gears stall etc.. more of a weekend warrior, above that not saying it can't be driving on the street but were talking more race engine territory. Of course there's gonna be overlap and depends on how well or poorly these combos are put together gonna have an effect. But I notice a lot of people think cause it's takes money and aftermarket parts to make 1.2 hp per cid like 490 hp 408 or 432 hp 360 means the same for all engines a 273 or 318 would make 328 hp and 382 hp those engine gonna need a lot less air flow and can, be gotten out of production heads. Does it make sense to build a 2hp per cid 318 636hp vs a 1.24 hp per cid 511 no but some like the challenge how on here when build building a high hp stroker 340/360 and people say they should go big block and they say they want the challenge.
