i made a mess after i saw this...

That price is par for the course - 45dcoe's are horrendously expensive - the price works out to what we will pay for the carb's only over here in RSA.
That said 45's is way to big they flow ~ 2100cfm in total - above what a street slant can handle. a 265 Hemi 6 e37 -e49 spec use that combo to push out from248 to over 300bhp stock - worked engines do 450 bhp...at 6500rpm
