(308) Building my motor.

[NFNSUS]

Thought I'd open a thread to help with the build of my 308.

I currently run a 253 ( sick of it. ) so I've organized a 308.

I'm dreaming of 200rwkw but to be realistic.. i guess 150-170ish?
The funds for this motor will be my weekly pay check which ranges from 250-500 a week. So i guess saving is a option when it comes to the expensive parts.

So i have a suspected 'blue motor' block.
Recently Hot tanked and honed with a brand new crank.

Where do i go from here fellas?

[NFNSUS]

^ Correction. Suspected RED block.

Also bored 40tho over

Flat top pistons
VN heads
Harrop or torque power dual plane manifold if going carby fed or using carby shape TB
reasonable cam
ST 2032 (non adjustable roller rockers) or ST 2033 Adjustable's

^^exactly what he said.. Keep us posted with pics and info, keen to see this done step by step.

[NFNSUS]

May take a few weeks for each post but will do.

Select a cam that will make approx 200kw that you can live with, cam selection will be the most important steps in the build, have your builder match the compression ratio to the cam and enjoy.
As the other guys have stated, VN heads will make good power but maybe a bit lazy on a stock stroke 308 with a carby.

forged flat tops
crane 286
YT 1.65 roller rockers
harrop manifold
quadrajet
VN heads
pacemakers
2.5" twin dumped at the diff
MSD dizzy, 6al and blaster coil
3000 stall converter
3.55 diff gears

and a LOTTTT of money saved for fuel.

[NFNSUS]

Noted.


Now to make a price list. :/

[NFNSUS]

By twin do you mean twin system or just twin tipped? O.o

[Wombles]

Should be an interesting build.

[ajvx01]

No one would tell u what tips bro

[ari666]

forged flat tops $600
crane 286 $500 inc anti-pump lifters
YT 1.65 roller rockers $700
harrop manifold $700
quadrajet $50 bucks, then $150 odd to have it built
VN heads $350
pacemakers $700
2.5" twin dumped at the diff maybe $1000, probably more like $1500
MSD dizzy, 6al and blaster coil dizzy $250 6al $400 coil $90
3000 stall converter $900
3.55 diff gears if you are really lucky $500, but you will have to watch ebay for AGES

and a LOTTTT of money saved for fuel.

for you. xxx

twin system of course, silly. twin tips are just gay. and you wont see them anyway exiting b4 the diff

[NFNSUS]

Aw

I have two blingy 3" dump tips, what I waste.


Thanks for the prices!

[ari666]

I agree with your list apart from the MSD stuff. Nice, but not necessary considering he's on a fairly tight budget
Factory blue/black HEI distributor/ignition will be every bit as good on this combo. Agree on the coil though, the Bosch coils are crap now they are made in China.

good choice of combo with 10.5:1 comp maybe 11.1...id go a solid cam instead!

[ari666]

or a roller...

[NFNSUS]

After a LONG wait, my motor has finally arrived!

[NFNSUS]

Motor came with a 272 solid.

[ajvx01]

Anymore specs?

[NFNSUS]

At the moment mostly everything is stock.

Hot tanked/honed red block
272 solid cam
Brand new crank
stock heads
stock manifold
and so on..
So i've been told.. knowing my luck, probably a load of bullshit but ohwell.


Bought it in pieces. Wanted the experience of putting a motor together. Parts list is above ^

[NFNSUS]

just sent this by the mate that went and picked it up..

hmm.

[NFNSUS]

Well.. I got ripped big time.

Thinking that just a 308 is kind of pointless.

Considering it'll be roughy what.. 5grand? Thinking of going 355 instead?

[drewVHSS]

so what came with the bundle to make you feel ripped?
you'll have to prep your block either way 308 or 355 so it's not much more to relieve the block for stroker clearances whilst it's being prepped.
you have a choice to either go with the solid cam setup and red heads or sell off the unneeded bits and use vn heads

do you have the patience to check your clearances and lash for a solid cam setup? if not... probably wiser to sell that cam and go for a hydraulic one or a roller setup.

[NFNSUS]

The pistons are all seized, the manifolds corroding, cylinder bores need to be re-honed. Heads need a lot of attention and so on.

I'm thinking of taking the block down to the machine shop and asking if it's worth stroking it. If not I guess I'll stick to 308?
