what cam?

[haubstr]

I have an L20B bored 30 over, an A87 peanut head shaved and ported, with dual solex 40's. I want a performance cam but not to wild. this isnt my daily driver but i'd like to take it to meets and to work sometimes.

 

 

anybody got suggestions on a cam?????

webcamshafts.com

Schneider

Isky

Colt and Shadebolt out of Canada

and maybe a few other brands out there

 

Bigger cams over about .475 lift should get new Bigger springs.

all will need new Rocker arms/Resurfaced

lash pads of bigger size and retainers.

 

allsaid and done add 500$ to 800bucks. More if other added things.

matchport intake and manifold if you have the bigger intake runniers. ect

I cked the Schneider site and they only do regrinds now.got to send your in to get cut.

 

Maybe try Webcamshafts.com and see who is a wholer for them as its cheaper than going throw them.

 

Isky had good prices if you can get to the link on the Datsun parts#s, 176 is the gouping.

 

best prices

Isky did the Cams in the Motorsport book anyways

regrind is better anyway, correct?

cause of the oil passages on them from the factory

 

while on this subject

Have tons of parts and keep forgetting which one is which

 

U20 stamped cam, is this from L20b?

I prefer New,

But regrinds work if thats all that out there. But I think you want bigger lobe centers if possible.

 

U20 is just a casting. I think its L20 but who cares.

 

some people get excited SSS cam in a L16/L18.

Who cares buy a l20 then its a 2liter SSS. same thing.

why i'm asking is because i was trying to run my truck with the stock cam and it runs like crap. i know the carbs are out of adjustment but what will the effect be if the carbs are in adjustment but the cam is stock.

[banzai510(hainz)]

I would put a weber DGV on there and see how it runs.

If good your cam is not bad but your carbs can be out of sync or just not jetted right or just junk.

 

ck timmeing again

Maybe adv it to 12-15DTDC with a light

 

I have a pair of 40mm mikini solex and they worked fine with stock motor and with a cammed ported motor(no jetting) maybe I got lucky.

 

also open up the top of the carb and cheack to make sure the jet blocks are tite

 

also ck to make sure the inner airhornsa(venturis are not loose) mine come loose every now and then
