By the vin number or enging number
it should be located under the plenum. u have to take the plenum off to replace it. not too bad of a job. just take your sweet time.
The 305 "HO" was actually dropped after 1986. In '87, the base 305 TBI was rated at 170 hp, the 305 TPI was rated at 215 hp.
Fuel Pump relay on my 87' Camaro 305 TPI is located underhood on the right side of the firewall, its the second relay of the 3 or 4 in a row
probably a 700R4

uhm no? 87 z28s only had 215 horsepower with a manual 5 speed and 190 horsepower with an automatic 4 speed I'm going to correct the above answer that is grossly incorrect. Please, if you don't know the answer don't bother. Let me do it so I can educate the masses on this type of stuff. Also, before answering use proper English and spelling and correct wording so others like myself can understand you. Thanks. The 1987 Camaro Z28's did NOT all have a 350 TPI. Most had the lowly 305 TPI. The 350 TPI for the 1987 Camaro IROC-Z had 225hp, not 190hp & it had a 700r4 auto/transmission. The 305 TPI Z28/IROC-Z that year had anywhere from 170hp to 215hp which could either be had with a 4 speed automatic tranny or a 5 speed tranny.

No, some IROC's are a 305 5.0 Liter and have a 5 speed manual. Total production for IROC's in 1987 was 38889, 12105 of those were 5.7L IROC's. ALL 5.7L IROC's were 700R4 Automatics, the remaining 26784 5.0L IROC's were available in Auto or Manual Transmissions.
Depends on what engine it has...
Chevy never made a 1986 IROC-Z convertible, not till '87 - so the answer is no.
