Ah, ok. The 4.3 V8. I thought it was a typo. My bad.

i had never heard of that. im sure its like all the other 305/307, no fun. i had a 305 for my 3rd engine first two where 2.8'* i got a good deal on 305 with a 700r4. it wasnt any faster than the 2.8 and i had a dd neon sxt 5spd., it was 2 tenths faster in the eighth than my hobby car, something seriously wrong with that. so i got a crate engine like apples and oranges feels like a muscle car now.

and the 305 is in the scrap pile out back because i couldnt sell anything except the carb for more than scrap value

It seems here at least that older engines like chev 305, 250 etc and ford 302 351 etc can be had in running condition for 300-500$
You can get nice engines for 1000-2000$.

i got the perfect running 305ho/4bbl from a 86 bird and the 700r4 for about 250. ran that for a while then traded the 700 to a guy with a 70'* 454 monte with a th400 when i got my crate engine. that was 1500 maybe 8 yrs ago
