The car is cool. To me it looks like a Falcon/Mavrick/Chevy Nova hybrid......

yeh, she's a little worse for wear at the moment.
I bought it witha "new" engine. Turns out the guy fitted this huge winged sump with no baffles. I did 10 very gentle "getting to know you" laps at our local track before i spuna bearing. That was over 2 years ago.
Currently the gearbox is reconditioned and ready, the engine will be finished this week and the interior and wiring is in total pieces. I have remounted the race seat, bought a wild twin thermo alum radiator, an accumulator, a million other bits and pieces. It should be startup in about a month and, with 600hp, I cant wait

RE: headers wont fit
oo ya good questionthe right hand drive may be a problem, and i also think (if my opinion matters at all) that 1 5/8 is kinda small i know they taper out to a 2inch but 1 5/8 is a very common header for a 302.. and what afrs did you go with? i have a 415 and was thinkin of the 205's
good luck ,Josh

I'm not sure if the heads are 205 or 225, just that they are the race series. I wouldnt use either on a street engine as the rev range is too high.
JB, I am pretty much coming to that conclusion, just that the budget has been blown apart and I was hoping not to spend any more on the engine side as I desperately need some diff and suspension upgrades. The car will not be able to use the potential hp without improvements in other areas, so I am looking at maybe a bit of a compromise for the short term.
Is there any issue with having headers too small or just going to limit max potential?

+ the air going through the 1.5" section will be at very high velocity, as it moves to the 2" section the gas will expand a bit and possibly help in "scavanging" gasses from the engine, much like a 2 stroke expansion pipe.... ??

IMO no downside to small(er) headers other than the max potential. I think these may do better than some people expect. There is a potential to move a lot of air through 8 1.5" tubes. + the air going through the 1.5" section will be at very high velocity, as it moves to the 2" section the gas will expand a bit and possibly help in "scavanging" gasses from the engine, much like a 2 stroke expansion pipe.... ??

if it isnt going to cause any harm, i will probably buy (or get a bud to make) an adapter plate to fit the existing headers and add some custom ones later.
