forgot to add true roller double row BRAND NAME cam chain and gear set.
as with any part, spend a little extra and use quallity parts.

are you doing a full rebuild? how much cash have got to spend?

[makka]

if i was building a 253 for the street this is what I would run:

acl flat tops
standard crank and rods
standard pre poll heads, tidied up a little.
edelbrock performer manifold or a modified standard pre poll manifold (the earlier the better)
re-jetted quadrajet (PM purpleLC)
rollmaster timing chain
and a nice set of extractors

buying as much of that second hand as possible you should be able to to do it for around $1000

Stroke it!

haha just kidding...

You can get a 253 to dance quite well with a good cam, carby and exhaust! They are cheap things you can do...

If you want to start getting really good power out of them.. ditch it and get a 308

sound better without, go better with I belive.

Dont the blue motor 253 VH heads have bigger ports, valves and better valve springs? Also dont they run a quaddie from the factory? Correct me if I'm wrong here.

[TerrA LX]

I wasn't really planning on rebuilding it, sorta just looking for bolt on ideas...

Anyone got opinions for the crossover pipe? Cut it or fix it? I've heard they go and sound better with out them??

Cheers,

Kurt.

if your motor is worn eg. compression down, blowing smoke or valve springs weak you not going to benifit from "bolt on's" better save and re-co the motor, you will have a far bigger gain.

blue were a better cast, but as for valve size, if they were any bigger they would be shrouded by the bore and probably even hit on a high lift cam.
if the springs were any better, thier age would dictate replacement anyway.
the late blues bid run a quad but not the same as 308.

I was referring to the other Tim, Tim.
I need a tacho that goes over 7000, so I can see what I am doing over that.
mine is not standard either......

[TerrA LX]

SHould I be getting a red or blue 253??

If you can get a second hand blue in good nik complete you will have elec ignition and 4bbl carb combo standard ready to go, preferably see it running and check comp etc, otherwise sitck with a red that needs a reco.
any reconditioned motor with a mild cam can be a very suprising performer.

[MRLXSS]

yeah... If u just want bolt on stuff.... Get yourself a 4 Barrel manifold and a Quaddy, Elec Dizzy, Exhaust system and maybe get some good heads for it if you want...
