appearently you don't understand, they had the same heads on them just a different cam, a little lower compression by not having as much dome on the pistons, and smaller carbs. The street versions were still a hemi headed engine.

The only major modification to the street heads vs the NASCAR heads was a reduction in the size of the intake valves. The shape of the combustion chamber stayed the same, "semi hemi".

BOSS 429s were detuned for the street...true...but they were ALL HEMIs

I remember a neighbor bought a brand new 1969 BOSS 429 Mustang the sticker on the window said it listed at close to $7000...when the next year my 1970 base - non "GT" Cyclone SCJ 429 complete w/ detroit locker and drag pak was listed around $4200...I think I paid around $3800...if I recall. So YES!!!.... BOSS Mustangs cost some bucks.....for reference a 1970 DeTomaso Pantara with the ford 351 cost around $12000.........I think we would all order up a dozen of each NOW for that price....but min wage was $1.60 back then and factory workers were making around $6/hr....so it was big money for the day.....

also...Im almost sure 428 were Fords hot number in 1969 ..at least in Torinos...if I remember right...except for the BOSS cars....the Only 429s prior to 1970 were Lincolns and Marquis....the Cougar/torino/Montego cars had 428s in "69

The Boss 302, Boss 429 and 427 SOHC were all built for racing and only put in a limited number of street machines to make them "legal" for racing. They were definitely FoMoCo's bad boy engines. The Boss 429 is barely a 385 series engine just like the 427 SOHC is barely an FE and the Boss 302 is barely a Windsor.

but the 427 never came to be. it was not allowed in racing and was not factory installed. they were however a parts counter item up until the early 70's if you had the cash.
