Cost Comparison - Overview
With all the places to spend your hard-earned money, you might ask,
“Where do I get the most power for my money?” |
? |
Trick lightweight pistons and small clutches cost $400 to $800. They offer better throttle response and quicker acceleration than stock, but definitely nowhere near a 20 hp improvement. |
? |
We have seen about 8 to 12 hp increase when comparing extensively re-worked carbs to stock carbs. |

Brzezinski Stage 1 Intake - Dyno proven 26 hp gain at 6,500 rpm. $639.00 |
? |
Flat tappet vs. roller cam - On a cast iron intake motor running 4000 to 7000 rpm there’s about 8 to 18 hp increase when changing from a flat tappet to roller cam. Cost of roller cam, lifters, springs, etc., is $850 to $1,100. |
? |
1.6 rockers - In all our testing with stock and modified intakes, we have seen, at best, a 4 to 6 hp increase above 6000 rpm when going from 1.5 to 1.6 rockers. In many tests we have not seen any increase at all. Cost of a set of 1.6 rockers is approximately $350. |
$ |
Brzezinski Modified Q-Jet Intake - Dyno proven 51 hp gain at 7,000 rpm. $949.00 |
|
We are not saying that roller cams, modified carb, 1.6 rockers, etc.
have no merit on a racing engine.
But for your hard earned money, dollar for dollar
a modified intake is a much better investment.
