I've searched but I just confussed myself further, so I thought I'd ask...I just rebult my 350 and wiped out a lobe, so time for a new cam. some engine specs, bottom is all stock crank and rods, used forged flattop pistons, new stock pushrods, new stamped rockers and springs. heads are the 305 416's (stock), the cam I'm replacing was a stock cam, one of my friends told me to find an RV1 cam it'll give me a little bit more boost and still maintain good MPG.

I've already got headers 1 5/8 to 2 1/2 collector, running 3 inch hiflow cat 3 inch pipe to flowmaster 80 series.

This car will be a daily driver, not a race car, just want a nice little toy...89 rs stock rear end, looking for a posi to drop in one of these days...

any help?

A compxe262 would get the job done nicely.
If you have a manual trans, an xe268 would work very well also, but with a stock stall speed convertor it wouldn't be that great.

Apeiron

An XE268 isn't that bad on a stock converter, but it does like having more stall.

Sorry, guess is should have mentioned...auto, stock converter..so is it the xe268? or do you have a better solution?

Ken

Apeiron

I don't remember offhand if the XE268 has too much lift for the 416s.

I didn't do anything to mine as far as grinding. I don't even think my machinist used offset locks, but he setup the heads for me, so I can't say for sure.

The xe262 works well with a stock convertor, and less than ideal rear gearing. With a stock bottom end keeping at high RPM for long periods is a bad idea anyway. It's a slightly safer bet.

I'd recommend porting the 416's if you have half a chance. It'd make a lot of difference.

Thanks, I'm not wanting to have high or keep the engine at real high RPM kinda defets the MPG factor, I just want t good running car with a little pop to her...so you are recomending the xe262 cam or something smaller?

the heads will be a winter project..just need to get the car running and pass emmisions...

Sonix

Xe262, any smaller is a shame in a 350. You'll barely notice the 262.
Lunati has a similar version, 60102 I think it is.

Sonix, I really appreciate your help...but, I have another question, after searching the web I found the Xe262 and reading it's advised not to use the stock rockers, springs, locks, and pushrods..I've already bought new stock stuff to replace the old ones...so should I go with xe262 and use stock springs ect..or just buy another stock cam?

Ken

Pushrods, rockers and locks should be fine.
Springs no. If you can in any way return your stock springs, do that. Exchange them, or somehow get new ones.
Are you absolutely sure you have stock springs? Do you have the spring rate on them, or brand? I'd recommend you replace those and get something worthwhile.

I can't in any good conscience recommend you get another stock cam.

Sonix, thanks for all your help, I'll shop around for a set of springs, what spring weight shoud I choose?

Yes, the set I have now are stock, got them off ebay for 20 bucks so not a big loss, no name no brand and no spring weight.

100/300. A basic 1.25"OD performance spring. Comp981 is a good example.

Sonix, do you think this kit is a good price?

No, that's the exact same price you'd pay on summit. I'd rather have it from summit.
Or just buy the cam and lifter kit, and springs - it's probably less.

Ok, found these...on summit..

now what would I use for cam lube? is there something I can get locally or do I need to order something special?

Ken

Sonix

Cam lube comes in the box with the cam. Buy some EOS from your local GM dealership and pour it in with your oil for break in. Follow the instructions with the cam on break in. You'll be fine.

That looks perfect, so you're looking at $240 or so, better than $320.

Thanks for all your help...I really like this fourm!!!

No more question for a while....at least I hope this thread will help others as much as it helped me.

I have brand new in the box all the components you will need to do the job right! springs, shims, seals, locks and the cam plus a new double roller timing set already drilled for offset timing bushing.

Ask some of the folks on this site about the fantatic deals on new parts they got from me.

I have these parts because A.) I did not freeze my design B.) So much time has past since I started my project(10 years) that new and interesting parts and technology has entered the market place C.) I never had a budget or cash flow problems.

let me know if you need the parts.
