sheet metal cut outs definitely look the best

Thought as much, so once you have a combo? how do you know what octane you need? just up the octane till pinging stops? surely not?

yeah I know. back on topic, how can we derive a rule of thumb for octanes relative to comp? Some believe you can run comps of 10:1 and slightly higher on 91. Yet dads zj in the shed will ping if he doesn't get his octane up to about 108 and that's about 11:2 comp. So really it depends on the combo?

Mate if im wrong tell me? just don't dismiss what I say, how on earth is anyone supposed to learn anything if people are like that?

want to run main switch in console like xe, but not xe switch was hoping to only have to run two wires in front doors for motor, run extra relays in console with the main switch and run what ever wires I have to in the rear doors.

how many wires do you need to pass inside the front doors for the power windows? just two for the motor?

Ive already got extractors, free flowing 2.5 exhaust with single muffler, slightly bigger valves on both intake and exhaust on the head. I think I have to run a converter with 517, think I might just buy a converter, seems like im going to be wasting my time if I don't, and im going to change from 3.27 to 3.45 gears. Ill have to start getting some bits together!

Hey guys, my weber isn't running the best, idle mixtures inconsistent and all over the joint, some times mixture leans right out. Like AFR's are 14.7 idle then sometimes between 12 and 15 at cruise and then if I come back to a stop it sometimes gets up to 16. Want something that I can tune real good to suit my engine. 250 is pretty standard just runs a 2.5" exhaust and extractors, street fire ignition, bigger valves in the head. What are other options over 350, 500, 465? What would be the best?

thinking I might go for the camtech 517, run a double row chain, some good valve springs, and some roller rockers on my engine

from what I remember yes 99% sure. its hf-5, cant really measure look at anything else its running on my car atm

well it is unmarked, so it could be an e head, alright cool.

another note, what pistons would I need to get comp around 10:1, im running the d head, this is it

so the 214 wakes up the crossflow?

the camtech 517 would definitely wake up the 250 though yeah, would have a bit more grunt?

so I can have some fun it, the 4500 isn't enough for me.

haha nope, but yeah a transgo kit, heard nothing but bad stuff about b&m

lacks size in what area, duration?, whats a good size for a hydraulic cam then? I want something that revs to 6k, makes a fair bit of torque, runs off standard converter with 3.45 gears. or cant 6k and standard converter go in same setup?

sure do, what sort of cam will run best with 3.45, I have 3.27 at the moment but want to run 3.45, don't want any lower.

it shouldn't thud to hard into reverse!, mine certainly dosent, full stage 2, performance bands, frictions clutches, heavy duty converter. next thing youd probably have to look into is selector alignment and play? in the trans itself, or maybe something more serious like the gear sets or planetary

im actually looking at running the camtech 528, I noticed a few use this, any good?

what solid?

ahkay cool. Well ive a fitted an innovate wb02, but yet to get some new leads, and plugs, on that note what do I gap the plugs for? think comp is 9:1

I wouldn't know. I definitely got that bit haha, balance my bottom end flexplate to balancer. he said resize for 302 Windsor bolts and nuts? are Windsor bolts bigger than 5/16"? Ahkay, so I am definitely safe to get me a 465 for a fairly standard 250, just will need some small jets. I want to hear anything.

an your pump could also be gone, when other things let go its generally due to heat, and c4's overheat when pump is no good, I just found out after having my c4 rebuilt that or a simple fix of low fluid!

i spoke to engine builder today about what I wanted to do. Mild cross flow, spin to 6500. He said I may have trouble safely spinning the standard 250 bottom end to that, but 6000 is doable with balancing. Straight away he said arp rod bolts. Even he thought with 230* duration, 550 lift and 110lsa a 465 carby still may overfuel the car.
