fitting tunnel ram to vk v8 black motor

[alltec]

just started building a brock replica its a stock 308. i want to fit tunnel ram with 2 x 650 holleys i just got and am going to stroke to 355. just after info on what heads and cam to fit and want other mods need to be made. want to to be good and strong but still suitable for street driving

fully sik!!!

I guess your not after a proper replica since your fitting a tunnel ram so bypass B cast heads and go VN-VT EFI heads.

As for a cam, what size wheels & tires, what gearbox & ratios are you running & what diff? What fuel do you intend on running? A tunnel ram wont exactly be legal as it will stick toofar out the bonnet so I guess its not a daily driver.

You'll want a decent head/cam/compression setup to suit the tunnel ram. They're really designed for high revving solid cammed engines. I believe redline make them for both B cast heads and VN style heads but the VN's have more power potential obviously.

at the moment was hoping to leave standard 10 bolt diff and trimatic for now just till its all up and running might change later i know i need to change stall convert ive got a set of 18 vz ss rims to go on. reliablity is a must. as for choosing between cheap and fast not really into racing it more after a tough looking cruise with some power to back it up

heheheheh. everything you say makes me laugh.

i think you need to do a little more research on tunnelrams before deciding to fit one, cos from the sounds of it you have NFI.

Harsh but ^ he has a point. Tuning twin carbs is not ideal for a reliable cruiser, and rams really are designed for all up top high revving power. I know they look sexy but they aren't the best option for what you are describing you want or even out and out power as their design is a bit dated now. A single plain high rise will out perform an off the shelf ram but what you are after would more suit a dual plain. Torque power now make a high rise dual plain which is great for tough streeters still retaining hydraulic cam setups and also looks the part. I suggest you research the TP high rise dual plain and run a single 750 or the like.

i apologise if i came across as being harsh. but ^^ eveything he just said

Tunnel ram and daily driver are just two totally different paths. you need to decide what you want, either a streeter, or a strip car. as mentioned above, go single plane high rise and you can have the best of both worlds, still rev's high, and can still be driven on the street (making sure you hit limiter at every corner haha)

hi all agree with everthing said. im first to admitt have no real idea after as much help and info i can get. im a carpenter trying to play mechanic. as i said it a project and a hobbie just enjoy the chalange of building something i know fu*k all about but am willing to put the time and research into producing a nice finished project

[vkberlina]

Your best bet for a good streeter would be VN heads, with an EFI setup, if you still want carbie then VN heads with a duel plane manifold, nothing too extreme cam wise, you need to pick your can to suit the gearing & wheels you will have, theres no point changing gear and dropping out of your power band or hanve to drive in stop start traffic at 1500RPM just to stop the thing from stalling. Go for roller rockers and hydrailic lifters, i have has solid lifters in a street motor and got sick of resetting valve lash.
When you build an engine you need to plan the entire build and pick parts suitable for their purpose.
Up to a certain point you can make good power then the faster you make an engine go the more unreliable you will make it

Saw this add and thought of this thread http://www.#################/sale-it...r-rockers.html

Notice he's selling a SOLID cam with it? Could save some money if you buy these parts but it won't be a sedate cruiser.

Ok this forum is even more retarded than I thought and blocks the link. insert

lol check this out:

1. BROCK replica
2. 18" rims
3. tunnel rams poking out the bonnet
4. solid cam
5. driven daily to work and back.

there are so many contradictions right there its not funny.

OP. its as easy as fitting a EFI 304 into your car. even if the engine looks like crap, it still has the wow factor and will have the speed and reliability you will never get from a solid cam tunnelram "brock replica"
