Please help a rookie with a question :: Okay fellows it has been a very long time since I have been on this site and taking some time to get acclimated to all the changes..
I just picked up a 67 Camaro with a stock Ls1 , brute speed blower cam, stock heads and a old Maggie blower _ I think it’s a mp122 or 112 I can’t member ..
The car put down 490 and almost 500 tq at the wheels ... I don’t know the boost but I think it’s maxed out for what the blower can do ...
Here is my question
If I replace the heads and go with a bigger blower cam can I get a good decent bump in power ? Let’s say and extra 30 to 40?
Yes I know it’s a stock bottom end and I’ve been told heads won’t make much of a difference ... I think if I can get this it will satisfy me for a while before I go spend 30k on a ls3 with whipple / tranny etc ..
Old cam specs 232/240 l .595/.608. 115 lsa
New cam specs 227/243 l .625/.615 115 lsa. ( tick stage 2 blower cam )
And for heads I was thinking tsp ascast 225..
Thanks for feed back in advanced

I don't see you gaining much in power as with the blower being maxed you'll likely be losing some of the boost it is currently making. I suggest adding a methanol injection kit to it, using 100% methanol. You'll pick up the power you're looking for by dropping the inlet air temps. Bob

My tuner said I could get 20 - 30 easy since I have added methanol injection just by bumping up the timing since it is currently tuned with an SD tune and with a very extremely safe tune (ATI D1 ProCharger at 10-12 lbs of boost).
It's an AlkyControl system - very reliable and easy to install.
Got's to have enuf injector and fuel too, though

Sweet looking 67, looks like a lot of money went into it-first thing that pops out to me is the fuel filter-while it may not be a rest., it just looks out of place, lol. You def need to know boost, current tune, etc.

From personal experience ( as I have been down the MP112 path), upgrading from where you are now will not gain you a significant power increase. I was in you exact position and spent a fortune only to gain another 50hp or so. Not worth it. My advice is to Enjoy where you are.
If you absolutely need more: I would consider a small 75 shot of N2O. It will certainly give you that extra bump & also drop your IAT’s. All of these options have consequences & further development to make them most efficient. In this case if you want to increase from a small shot the N2O will require an adjustment to timing to keep it safe, that means either a computer/ management system upgrade of some sort or when you drive around with the “bottle off” you will have to have a dumbed down tune ( reduced timing) which is a bit anticlimactic.
IMO: stay where you are and enjoy that TQ. The #’s are just that. The TQ curve you presently have is the envy of most street car guys !
