is this street legal

[borowskirace]

@mancilla903 Not to be a smart ass, but it depends on the street (i.e. local laws). The car this motor's in does 330ft wheel stands. It'd probably be a little out of control on the street.

john kaase says tunnel rams dont help that much over victor intakes,, I dont believe him, I had basically stock bottom end 460 (with arp rod bolts) , stockish 460 heads with valve job and flat tappet cam and that thing would scream to 7,000 grand and not miss a beat with wiend dual tunnel ram... made a believer out of me... 540 hp. looks like another believer here... nice motor..

Is it running on alcohol?

[sniperv25]

Not gonna lie....I'd love one of these shoe-horned under the hood of my foxbody.

[rodman23t]

it takes a heck of a lot of crankcase pressure to pop off a breather cap. thinking a vaccum pump might be a good idea

[lostwill86]

i'm not gonna lie i thought it would be more powerful. but the sound is summit else!!1

woow nice motor

[mudcharger]

what blew off of the valve cover at the end??

[borowskirace]

@mudcharger The breather popped off.

[madtownmadman]

@mudcharger That was caused by blow-by. Cylinder pressure getting passed the compression rings, when the throttle is abruptly closed, while the engine was at max rpm. That closed throttle creates a helluva vacuum.

Will That Fit A 94 Stang??

[borowskirace]

@Twinturbocamaro511 It currently resides in a Pinto.
