I am thinking of ordering a cam from Summit the SUM-K-1103
the specs as I know them are 272/282 advertised duration
214/224@.050 duration lift .442/465 and the lsa is 112 going in a 305 30 over with ported and polished 081 heads Holley Street dominator intake and a 600 cfm Holley no emissions to worry about. Headman Headers and y-pipe 700R4 with stock converter and 3.42 gears

 

 

What's your price budget, I wouldn't go with a Summit cam. I asked this a while back when I wanted a cam, and they're based on 80's technology. A cam is a great way to boost power, I'd recommend the Comp 262xe for your 305.

 

I use that same grind in my car. (Blue Racer) It's a good street performance grind. Works right off idle to 5500 rpm. Some things just don't need improving (Mark). Car runs 13.0's with Vortec heads. Smooth idle, high vacuum lots of torque and power
for the street. You'll like it.

 

Hey f-bird thanks for the feedback. I am glad to here you had a good experience with the cam I have selected. Was your motor 305 or 350. I figured the Summit cam was a good grind for the money since they are made by Crane. Old technology I would think not, coming from Crane but thanks for your 2 cents Mark but it didnt really offer ant proof that the cam would not be a good choice for my application

 

Um ok, just tellin you what the more experienced guys told me on the board. I think that is proof enough. I listen to RB and Vader anytime they talk.

 

that was on a 350

 

Granted unless you're trying to squeeze out every last bit of HP, then a Summit cam should be fine. Just like if wanting to use Flowtech heaaders, but you get what you pay for.

 

Why do people always think that you get what you pay for. This is not always true. Granted Mark you love comp 262 cam its all over the place and thats all you suggest and I am glad it worked out for you. Truth betold there are other companys to buy things from. Sometimes we forget that we sometimes pay for the name and bragging rights to the name. Every part has an application what worked for you may not work for me or my budget. The only thing I asked was this too much cam and some others experience with it. I am not putting you down Mark, but I am a father of five with a wife and an ex-wife constantly in my a$$ with not a whole lot to spend. Just looking for bang for the buck.

Thanks for the input f-bird88 how do you think that cam will be in a 305. I am guessing about the same as it was in your 350

 

Actually, I don't have a 262, I have the 268, and I researched cam choices extensively before I bought one.
262 seems to be very popular for a 305.
A lot on these boards raved about the XE series, top notch technology used on them.

I hear ya about money, wow 5 kids huh, I'd suggest you and your wife sleep in separate rooms.

I'm in college and money is tight as well, but I hate to skimp on things, but that's just me, I'd rather be broke and be a few 1/10ths faster.

 

Well Mark: when ya get out of the 15 sec bracket we'll add 'er up
$ $

Just kidding... Heee heee hee

 

ouch, low blow. I swear after the new heads, carb, and exhaust, if I'm not, I will either a) cry b) get a for sale sign or c) shoot myself.

lol.

 

Hey Mark dont shoot yourself. This forum is one of the things I look forward to in life. I can always count on you to rply in some way. It gives me something to do away from the kids for piece of mind. (15 sec Bracket) really. I am hoping for 14's some day even with a 305. Hey f-bird88 how do you think that cam will perform in a 305? What kind of Hp and torque ballpark?

 

Yup, something was way out of tune on my car, I just wanted to start over, and work from there.

 

So......you never were able to figure out what was out of tune I take it. What do you think went wrong

 

well if u dont get out of at least the 14s u should really consider taking it to a mechanic u trust to really tune and dial it in for u cuz i dont see how u could run anything lower than high 13s with all those new goodies going on.

 

Looks like I was running really rich, I'm at college, and the car is at home, so I didn't really have a lot of time to trouble shoot, so I thought I would get some new stuff and go from there. I also suspect timing issues. Which would have been an easy fix, just didn't get around to checking into it too much.

 

oh i agree completely, depending upon traction, as I will have to wait till after xmas to do suspension mods.

 

get a set of hoosier street drags or whatever they are....... my buddie had them on his 71 c-10 shortbed dropped, rims, 350/350, th-400, blah blah..... they hooked great.

 

Well Mark: I got one more set of these 305 heads saved for ya.

....Just in case...... hee hee eh....

 

Mark Did you degree in your cam when you put it in? lol that funny f-bird88 you like those 305 heads dont ya.

 

LOL, I may tell my brother about those, as he has a motor from a 74 Chevelle with stock heads...

 

nope didn't degree the cam... should I have?... I thought there was something about Comp Cams where it wasn't necessary to degree it in.

Funny thing is, when I first finished the install, after the cam was broken in, I took it for a trip. Well, I had some NON SA rockers on there, which I didnt' realize at first. but when I floored it, it really planted me in my seat, but then i heard 2 loud pops, rockers slid off, think any damage may have been done. The car seemed to run fine afterwards, just slow.

 

I have a set of 416? 305 heads for ya Mark just back from the machine shop.

 

nope sorry, I just ordered some aluminum ones, only 64 cc though.

 

Crane cam has a nice article about degreeing the cam what you essentialy do is check the grind of the cam for accuracy. I have heard of cams being of as much as 6 degrees, ie bad cam marks on gears bad lock positions on gears Cams not ground right mixed timing sets ie wrong gears with chain combo. It maybe worth looking at before you tear the whole thing down. Certainly a degree kit is cheaper than a set of heads or Comp Cam in that matter.

 

Only 12,900 posts to catch up to Mark
waaaahoooo lol

 

lol

 

my buddie has the greatest set of heads on his 89 s-10....... hes got old chevy 302 heads..... 58 ccs..... ported to the *****...... they work well on his 450 hp 350...... i dont know if theyd be forgiving for anymore than that though....they are great if your looking for compression...... its always best to up compression with the head rather than piston.... unless u are upgrading from a dome to a flatop with vavle reliefs........ but neways those heads are rare and if neone wants a pair talk to me hes got another set.
