In trying to get a feel for what I can expect performance wise from my 4.9 powered Monte I did some comparisons to stock vehicles I have had experience with in the past. One of those was a good friend's then new '85 Monte Carlo SS. The '85 SS Montes weighed right at 3400 and were equipped with the L69 305 HO which was 9.5 to 1 compression and rated at 180HP @ 4800 RPM and 225 LbFt @ 3200 RPM, the 200-4R OD, a 1900 stall torque converter and a 3.73 differential. 0-60 averaged about 7.9 seconds with an average ET in the 1/4 of 15.9. I remember riding in my friends and recall that it "felt" pretty darn quick for what it was. Not fast but definitely fun.
A stock '95 Monte Z34 averaged almost identical 0-60 and 1/4 mile performance, maybe a tenth or so quicker. My '95 Monte weighs around 3400 Lbs and currently has a FDR of 3.43 but I have been advised even this may be too low for the 4.9's likings, we shall see 'cause it's stayin'. As we all know the 4.9 is also 9.5 compression and is rated 200HP @ 4100 RPM and 275 LbFt @ 3000 RPM. More HP and TQ than the 305 HO and at a lower RPM. Hmmm, this could be VERY interesting.......... it may not be a great 1/4 mile machine but I can see 0-60 being a WHOLE lotta fun !
