I've got a 1975 2.0 engine on carbs.
Engine is in good shape, but I might go to a 6 in the future. In the mean time where are the biggest HP bangs for the buck for my 2.0? (Assume everything is stock other than the carbs, and going back to fuel injection is not an option) Thanks in advance |

tune up and valve adjust
back date the heavy bumpers get non '75-76 heat exchangers/exhaust. learn to enjoy the momentum driving experience |

What's next on the scale of cost to benefit? Weight, both yours and the car. Given the stock HP numbers every pound of weight reduction will give you free HP ... (IMG:style_emoticons/default/bye1.gif) |

(IMG:style_emoticons/default/bye1.gif) The car will be a fibreglass fender& bumpered GT so weight is gone ( and I'm skinny) So, what can I do to the engine short of a fire breathing monster? My last one was a Raby 2316, but I don't want that level of investment, I just want to wake it up a bit Maybe take a zero off the price of a full blown RAT motor Looking for engine ideas. What do they respond best to? I could go cam, heads, displacement and compression but together that gets pricy. What my incremental staring point without diving into the deep end again? The header and carb tuning suggestion is a good example. I'll do that. I might even stop there What's next just above that. Just cam? Clean up heads? Is there much to be gained there alone or will it require a bunch more parts to make the cam work? Or is shaving the heads for a small boost in compression a better idea than a cam? Other? Or is much more fruitless for the cost/ effort without doing everything? |

Ignition. At the very least pertronix, next step Mallory type ignition system or some kind of upgraded dizzy to get the best, most consistent spark you can. Won't be huge gains, but it's an easy and fairly inexpensive way to get the most out of what you have.
Cam will make a noticeable difference, as would flat top pistons (euro spec mahles) but then you're getting into splitting the case... |
