That was so funny. No I do not know what he meant either but I like the stock cam idea with 280rwhp. But I am not sure how one would even acheive that..like Grady said..it has to rev.
the metal used in 302 blocks produced in mexico had a higher nickel content I believe so they made the mains wider i believe? Thus its a stronger block then the regular 302.
It was kind of like in this order of stronger blocks. The stock 302, mexican block, and dart block. Dart block still being the much better block but the mexican was still better then our 302's
You want to know what i mean try reading the post replying to it
Oh, sorry. I missed that. BTW I was not laughing AT you but at Chris's response to you.
You are correct, the Mexican blocks are stronger, but are old, and not set up for roller cams. So you have to spend a whole bunch of money converting it to a roller motor to run a stock cam. With the power levels consistent with a basic H/C/I combo, a late model roller block is sufficient, and it is much cheaper to setup.

actually retrofit kits arent really that expensive.

Yeah lol. When I wrote that I knew it didnt make sense but I was tired and said w/e. But what I meant was that I didnt think it would be feasible to make 300RWHP on the stock cam. However with the right HCI setup 300+ is very doable. However 280ish with the stock cam, and its manners is still a very impressive number.
My understanding is that it has more to do with the lift of the cam than anything else.I thought I read somewhere that if you did the retrofit kit you were forced to run a small base circle cam. I was under the impression that the only way to throw a standard HR cam in there was to use the link bar lifters.
I also disagree with the post that you have to lose mid-range power to get to 300rwhp. I'll bet you my next pay check that if you told a custom cam grinder that you were adding aluminum heads and a new intake, and want a cam to improve power all through the power band AND have a higher peak he could do it for you. Peak horsepower doesn't move the car, average horse power does, this is why custom cam'd cars go faster, they have more average horsepower. Also why long tube headers are bomb for the street, they add little to nothing over shorties peak but the average horsepower increase is noteable.

Whereabouts in Oregon are you located?
Grady, you should easily get over the 300rwhp mark by swapping in a bigger MAF, TB, and higher-flowing catbacks. You might even get over 310, and that's without losing low rev torque. I'm surprised you didn't think of that already.
Well
Since you brought it up
When I built the combo I wanted to not compromise on certain parts :Word:
You know stuff like h/c/i
So ... money was spent there as opposed to other parts
I knew the small gain items could be replaced later
TB, Meter, and Catback would certainly fall into that category
The OEM meter was just pegging but not by much
I did upgrade the tb and meter but have not been to the dyno
I can say the difference starts to be felt at mid range and gets more
noticable as the rpm's climb
As for the catback ... I'd bet a gain of like 5 rwhp would be about
the most you could expect
Several years ago I remember a member who I knew was the kind of
fellow who posted up stuff that could be considered to be reliable
He had a full on 347 with all the good stuff to support it
Believe it or not ... He was still running the OEM catback
HE went to an aftermarket catback and only picked up 10 rwhp
I have always felt if that was all he got
A combo of 50 less cubes will flow less air
therefore
The gain from a catback would have to be less on a smaller motor
anywho ... Just a random thought or two

Well, 5rwhp here, 5rwhp there. It's those little things that can make the difference between getting over the 1.0rwhp/ci mark (0.9rwhp/ci for an automatic) or staying under it.
I think an H/C/I 302 would gain closer to 10rwhp than 5rwhp from catbacks, and if you don't want to part with your existing tailpipes you could just replace the mufflers.
