[Sprekitek]

A pissed big block!

That thing must smell good!

@LoZioFBV far as I know a big block don't fit in a GTR this in a small block you can stroke and bore an ls7(smallblock) into 454ci.

You are an artist! I want one!!! I bet they cost a fortune... weeping

[davrianman]

Yep. The headers are 2". Standard Ultima are 1 3/4" and are very restrictive for bigger engines. They sound awsome!

[feluke]

Are these 2" headers??!!

[NeumannAlfred]

That engine sounds like a thing straight out of hell!!! Fantastic, how many HP? Would love to see it in an Ultima GTR....

[shmana]

wires everywhere..lol

A 2 barrel firing back at you is scary, dual quads must be terrifying.

[davrianman]

Flames were due to a weak mixture (which we were correcting during the test). Bloody scary!

[crv26]

is it carbed? if so why did you choose that over fuel injection? Engine sounds ruthless!!

[AdangerousRETARD]

@crv26 no its not carbed thats why you cant see the carb on top!

[jeffgooloolie]

At 0:44 you can see flames coming out of the air intake.... Why?

[supervegano]
