Product ID: EVO-Bullet
Bullet billet block 4G63 or 4G64
Bullet billet block 4G63 or 4G64
Bullet Race Engineering’s 4G63 billet block offers substantial improvements over the OEM cast block. Rated to 1700 HP, the Bullet 4G63 is 20 Kg lighter than stock at just 29.1 Kg.

It is significantly more rigid and durable than any cast block, and features four-bolt main caps and increased deck and cylinder wall thickness. It’s available as a dry block for drag applications, or a wet block for circuit racing and street use. You can also have the block "wet" but the deck dry which is a halfway house and offers the best of both worlds. However this requires the head and block both be fed water rather than it travelling through the head gasket.

ND also offer our fire ring head sealing solution (as a cost option) for this block, coupled with the supplied 1/2" studs its a proven solution! We're trying to keep both wet variants of block in stock, fully dry is to order only though as drag racing isn't so popular here in the UK.

Our own twincharged Swevo Evo 9 runs this block at the heart of its 1250Hp twincharged zero lag engine! People worldwide running these blocks to over 100Psi of boost and making 1700Hp and MORE!

The bore comes unfinished so needs boring to size, we run most of these at 85mm to 85.5mm to leave as much liner thickness as possible, but it can accommodate bore sizes up to 87mm. Machining charges are NOT included in this price.

The block is offered in both 4G63 and 4G64 (+6mm) deck height plus also available for Evo 4-9 AND Evo 1-3 configuration!

Price: £6,750.00 (£8,100.00 Inc. VAT)
