i had a motor making the same power.. one was efi, one carby. the carby feels more responsive under foot to me. but thats just my opinion Some original photos have not been recovered yet.

With the fuel injection i was thinking MPFI.....wat sort of fuel injection system do you guys think would go best for performance and street use

i would actually like to run some trumpet style mechanical injection..

could u esplain to me about that kind of setup

you dont want to run it..

I would just run the delco that the vn/vp uses or even kalmaker initial cost is a bit more but works out cheaper because you programme your own engine on a laptop rather that payiing for a new chip every time you change something. Madvk when are you going to go efi ? i've done a few into vh/vk's if you need any info/hand. Some original photos have not been recovered yet.

why do i not want to run it......i've never really worked with fuel injected V8's so its still a learning curve for me.

because mechanical injection can be a serious headache, and i'll only do it if i keep building my big block

Mechanical Fuel injection isn't the best thing to be running on the street. I would either stick with the carby or go to EFI. Some original photos have not been recovered yet.

thanks for that demon8, you put it into words that i could Some original photos have not been recovered yet.

Thats going to be a mean Big Block Epitaph. Some original photos have not been recovered yet.

Street use there is noooo reason whatsoever to choose a carby over efi, efi will get better economy, be more responsive and make a better power/torque curve, carbies just dump fuel down the guts when the pedal is pressed, with no control... efi is all optimised in precisional harmony i also currently own a 308 and a efi v8, the efi v8 >>>>>>>>>>>>>>>> carby, hence the carby 308 is getting vn heads Some original photos have not been recovered yet.

I am in the IT Field Epitaph. I suppose it depends on how you look at it sinister. MPFI = Mechanical Petrol Fuel Injection ( Mechanical) MPFI = Multi Point Fuel Injection ( Electronic) I took it as he was asking about Mechanical injectionm yet he may have been talking about multi-point EFI. My Bad.

LOL at vk355 mate a 253 is piss weak allways will be allways have, on the topic, im going to go sc or turbs, so any one recomend boxing in the carby to presurise it or any one got any other ideas?

I will second that one, my dad had one in his ute, sounded tough but when I drove it .... holy crap this things gutless. No joke my sisters 81 corolla had more guts, but in saying that any motor will go hard with a bit of work and alot people like the 253's so I won't bag them too much.
