-Crank scraper (Would this not go against the no internal rule????)
-Some kind of crossover for exhaust, right now it’s just dumped after headers (An xpipe has been shown to make more power, but the most power can be obtained from dumping around 18" after the collectors)

e85 would be worth it to me if gave just about any gain. Let’s say 5hp or more through pushing timing etc

Crank scraper I think I agree, but they didn’t exist back in the day so they have y really been addressed.

Yea I have mine dumped at approx 18in but wasn’t sure if doing some kind of H pipe on the dumps could help or not. Probably splitting hairs, but that’s kinda of the game I’m playing…

Any sort of crossover is really just a crutch to improve a collector design that can't (due to clearance, universal fitment/packaging, and/or the need for an emissions compliant exhaust system) properly or ideally scavenge. If header/collector design and length is optimal for your application, or can be made optimal, then there shouldn't be anything to gain from a crossover (other than added weight, which obviously goes against the goal here).

But this does bring up a good point, i.e. "splitting hairs". You might be able to gain a bit of power if you play with header and collector design, getting optimal flow for the exact characteristics of your engine. This would obviously require some very expensive custom headers, the gains would be small as compared to the cost, but it's something you could do while staying within the "rules" - and being #1 is never cheap! Also, consider thin walled headers for weight savings (e.g. 18 gauge rather than 14, etc.)

Hmmm that’s a solid point. I wonder what that would actually cost 🥴

I gained a tenth and mph with E85 on my small cam head intake car.

Crank scraper and baffle I gained another tenth and mph with 6500 shift points.

I gained nothing going from powerbond to ati pulley.


​​i gained a ton going to Pro stock Ram air,big TB and intake along with speed density. But I have ported 799s Mamo 102 etc

I can't get vacuum pump to mount with this ram air. I'm sure it would be worth some power.


Look into titanium hardware as well in the motor.


I'd go with biggest stock LS1 cam off an early car. And flow some stock heads and get ones that are nearly identical.

Back in day stock internal guys could do 10s at about 2900 pounds

Hi Mike. Still not happy you ripped me off on the vacuum pump. “New in box Fbody kit” and it was missing pieces and not a Fbody kit.

What Im currently thinking but open for input:

1 7/8 wrapped longtube headers
True duals/dumps
Mamo ported 102mm fast intake/TB
Chrs1313 pro stock ram air
SLP under drive pulley
Meziere electric water pump
GZ Motorsports vacuum pump
Proper tune
NGK 55
MSD wires

Up for consideration/discussion:
- aftermarket/upgraded coils
- e85
other…?
didnt read through every reply so not sure if its been mentioned but 1.8 roller rockers would be a good one

i also dont think it would be at the power level to need 1-7/8 primaries so 1/3/4 might get you more torque lower in the curve

I would think if you want to go all the way you would have to run it on alcohol. Or some kind of meth injection into the ram air tube. The colder you can get the intake charge the better.

e85 is a good compromise if you dont want to go that far but getting it out of the pump is a crap shoot unless you have a reliable source or you want to buy a drum.

Bolt ons are great fun. Teaches you how to make the car accelerate vs just trying to throw power at it.....and more often then not the bolt on combos seem more effective.

I always viewed bolt-ons as the items that supported the power that you’re throwing at it. Take a throttle body for instance. If you’re making X amount of power you need X size TB. That sort of deal.

I’d say a stall and a good set of tires.
