Cam selection guidance.

You're going to get very minimal horsepower from a cam at this point in the game

Yep. Either save the money or put it into something else(shot of nitrous maybe).


I'd try to save up and get a used set of aluminum heads if i were you. Or maybe look at the gt40 threads to see what guys have.


I like to remind guys to figure out their end goal for their car before they start getting parts here and there. If in 2 years you want a turbo car, or a n/a monster, then start laying the foundation for that now. You may sacrifice a little more now, but you'll save money and time if you know the direction you are going.

Here ya go....this should help:

Will a cam give you more hp

Yes for sure ... but ... Is it worth it if you look at the big picture

I'm no cam Guru but I do feel I got a basic understanding about how all
the various parts work together ... good or bad

You got a basic GT40 combo at this time and they usually run in the
range of 245 to 275 rwhp dynojet sae calibration

The whole GT40 combo thing was designed around OEM Iron heads
that have VERY POOR exhaust efficiency

Those combos also were setup for a bit of extended rpm range
but
You gotta stay within reality here :Word:

I mean ... heavy roller lifters and wimpy OEM v springs won't do much

So ... having laid all that down you should see how limitations are in place

Talking big 3 (h/c/i) If you move away from OEM and go to aftermarket ...

Unless you go aftermarket with ALL 3 you kinda shoot yourself in the foot
as far as getting the BEST performance

I'd say those shortys are holding you back big time in your low/mid rpm
range

For a NA street combo ... LT's make such a difference in that area

For what you now got .................

I'd think a custom cam and sharp tune would give you .......
The most go for the least dough

The cam guy will take what you now got and be able to tell you what is
possible AND he can also tell you what might be possible if you go to
different combo parts

My reasoning is the cam and tune will give you good gains and still stay
within the narrow range of rpm you got to work with

NOW ... you gotta ask yourself
What gains if I went with the big 3 aftermarket combo parts and stayed NA

290 to 310 rwhp dynojet sae calibration

To get the best performance you gotta have all the supporting parts which
you certainly don't have at this time

So ... You got a lot of cash laid out for not all that much more hp

Maybe some juice or a blower might be considered

Here are some NA combos based around OEM IRON heads
and Aftermarket Aluminum heads

Hope this gives you some stuff to think about
